Leader Skills source contract

Updated 13 September 2026. This is a primary-source contract for the optional Leader Skills module from CHOAM & Richese. The later first runtime prototype records connected behavior and remaining gaps. This contract does not enable the module or certify its combinations.

Rihani and permanent Traitor markers — 15 October 2026

The shared canonical Traitor snapshot now includes an optional permanent removed zone derived from Moritani's retired victims. Rihani preserves that zone in its full before/state receipt and cannot peek, draw, return or rewrite one of those cards. Existing used-card exclusions, native Tleilaxu Face Dancer classification and both original skill bands remain. Old absent-zone JSON receipts keep their existing body/signature. Focused physical-transition coverage verifies this consumer; the coupled native Nexus proof is not a claim of a new full native Rihani/Moritani or saved-game assurance campaign. Canonical shared role/census and evidence.

Sources and local evidence

The governing source is Gale Force Nine's twelve-page English CHOAM & Richese rulebook, especially pages 8–9 and its Q&A on pages 11–12. The original GF9 URL now redirects or returns 403 in ordinary clients. A byte-stable copy of the publisher-authored file was retrieved from a readable rulebook mirror. The designers' expansion page links the same GF9 rules.

Card names and face text were checked against a photograph of all fourteen physical cards. The four clearest individual faces also appear on the Future Pastimes designer site. Designer Jack Reda's complete card walkthrough confirms every value and explains how the two effect bands interact.

The persistent archive is /home/quintine/.local/share/dune/sources:

• choam-richese-rulebook-en.pdf and its layout-preserving .txt extraction;
• leader-skills-tabletopfinder-all.jpg, the fourteen physical faces;
• leader-skills-future-pastimes-4cards.jpg and choam-richese-future-pastimes-components.jpg, designer-site images;
• leader-skills-designer-video-page.html and leader-skills-designer-video-auto-transcript.txt, the timestamped designer walkthrough evidence; and
• leader-skills-source-provenance.txt, with retrieval URLs and SHA-256 hashes.

The transcript is auto-generated, so names and numbers below follow the card faces when its speech recognition is imperfect. The effects are paraphrased rather than reproduced as card text.

Physical inventory and effects

Each card has a face-up effect above its illustration and a second effect for the assigned leader when that leader is actually used in battle. “Normal” below means the first effect, which is publicly available while the skilled leader and card remain face up. “Skilled battle” means the lower effect. When the skilled leader is used in battle, both the first effect (when applicable) and the lower effect may apply, subject to the card's “other leader” wording and the nonstacking exceptions below. The designer walkthrough establishes that the +1 “other leader” effects and the skilled leader's +3 effect do not add together; Suk Graduate's two rescue effects are also alternatives rather than a cumulative four-force rescue (designer explanation, 4:34–8:23).

#	Card	Normal effect	Skilled battle effect
1	Bureaucrat	Once in each phase, when another player pays at least 5 spice to a player other than this skill's owner, the owner may redirect 2 of that payment to the Spice Bank.	The opponent reduces their battle total by 1 for each stronghold that opponent occupies; Bene Gesserit advisors do not count as occupation for this penalty.
2	Spice Banker	Once in each phase, when another player pays at least 4 spice to the Spice Bank, place 1 spice in front of this faction's shield for collection in the Mentat Pause.	Commit 1–3 spice with the Battle Plan and add the same amount to this leader's strength. This payment is separate from spice used to make forces full strength.
3	Diplomat	A single Worthless card in the owner's Battle Plan may stand in for the defense used by the opponent in that battle, provided the owner played no defense; discard the Worthless card afterward.	If this faction loses, retreat up to this leader's strength in undialed forces to one empty adjacent territory that is not a stronghold.
4	Mentat	Before Battle Plans, name a specific weapon and ask whether the opponent holds it. They reveal that card if held; otherwise they reveal a different Treachery Card. Revealing the named weapon does not commit it to the plan.	Add 2 to this leader's strength.
5	Suk Graduate	After winning a battle in which the winner loses forces, return 1 such force to reserves instead of the Tleilaxu Tanks.	After winning and losing forces, prevent up to 3 from going to the Tanks: leave 1 in the battle territory and return the remainder to reserves.
6	Rihani Decipherer	After winning a battle, secretly inspect 2 random cards from the Traitor Deck, then reshuffle them into that deck.	After winning, draw 2 Traitor Cards. Keep 1 by revealing an unused Traitor Card already held, then shuffle that revealed card and the unkept drawn card into the deck.
7	Sandmaster	When moving any forces into or through a territory containing spice, the faction may immediately collect 1 spice there, once for each territory traversed.	After winning a battle in a territory that contains spice, add 3 spice to that territory.
8	Smuggler	When shipping forces from off-planet to an empty territory, one additional force may accompany that shipment for free.	When Battle Plans are revealed, collect spice from the battle territory equal to this leader's strength, limited by the spice present. The general survival rule still applies.
9	Planetologist	For a movement, either add 1 to movement range, capped at 3, or move forces from two different territories in the same movement when both groups have the same destination.	In the weapon slot, reveal a green Special card other than a Cheap Hero and add 2 to this leader's strength. Discard the Special card after the battle. The card is used in place of a weapon.
10	Warmaster	Other leaders gain 1 strength when their Battle Plan contains at least one Worthless card.	Add 3 to this leader's strength when its Battle Plan contains at least one Worthless card.
11	Master of Assassins	Other leaders gain 1 strength when using a Poison Weapon.	Add 3 to this leader's strength when using a Poison Weapon.
12	Swordmaster of Ginaz	Other leaders gain 1 strength when using a Projectile Weapon.	Add 3 to this leader's strength when using a Projectile Weapon.
13	Killer Medic	Other leaders gain 1 strength when using a Poison Defense.	Add 3 to this leader's strength when using a Poison Defense.
14	Prana Bindu Adept	Other leaders gain 1 strength when using a Projectile Defense.	Add 3 to this leader's strength when using a Projectile Defense.

The designer explains Planetologist through Rihani at 9:53–14:08 and Diplomat through Mentat at 14:11–18:56. Those segments confirm the less legible photograph details: Diplomat says “undialed,” Spice Banker spends 1–3, Rihani draws 2, and both Warmaster bands require at least one Worthless card.

Setup, visibility and lifecycle

Leader Skills is an optional variant. It may be included independently of the two expansion factions and independently of Advanced Stronghold Cards.

The module changes setup order. After positions and Bene Gesserit prediction, deal starting Treachery Cards, including the Ixian start-of-game draw. Deal two Leader Skill Cards to every faction; each faction keeps one and shuffles the other into the skill deck. The kept card is placed face up in front of the shield, and one eligible leader disc is placed face up beside it. Setup then continues from Traitor selection. The card and assigned leader are public, so Traitor choices occur with that assignment known. The CHOAM Auditor is explicitly ineligible for a skill. GF9 rulebook, pp. 7–9

The skill remains available while the assigned leader is alive and both the leader and card are face up. When choosing a battle leader, the owner may:

• leave the skilled leader and card face up, preserving the normal effect and publicly proving that leader is absent from the Battle Plan; or
• move both behind the shield. If the skilled leader is selected, put both its disc and skill card into the battle wheel; both effect bands remain available when applicable. If another leader is selected, neither part of the concealed skill is available in that battle.

After battle, a surviving skilled leader and its card return face up in front of the shield. If the leader dies, its skill does not apply in that battle and the skill card is shuffled back into the skill deck. Later, whenever a faction revives one of its own leaders while it has no Leader Skill Card, it may draw two skills, keep one, shuffle the other back, and assign the kept skill to that newly revived leader. The rules give no voluntary reassignment between living leaders. GF9 rulebook, p. 9

Skills that mention a card type require the physical card in the Battle Plan to be played in that role. A multi-role card does not qualify merely because it could have had the named role: the rulebook's example requires Chemistry to be committed as a Poison Weapon for Master of Assassins. Skill resolution precedes faction abilities; the printed example orders Mentat before Atreides Prescience.

Capture and official clarifications

The user's requested fresh search resolves the skilled capture's public state through its unique, publicly assigned card's required movement. See the capture interpretation and its precise limits. The 13 October 2026 replacement ruling then resolves the captured-card replacement question: the original assignment is retained and no replacement card is drawn while it exists, while ordinary and Ghola revival of another own leader is unaffected.

When Harkonnen captures a skilled leader, the skill card travels with that leader. The captor may use only the lower battle effect and only when using that captured leader in battle. Thus a captured Spice Banker cannot collect the normal payment trigger, but may spend 1–3 spice for its battle bonus; a captured Mentat receives its +2 battle bonus but not the pre-plan question. GF9 Q&A, p. 12

The same official Q&A settles these boundaries:

• Mentat may ask its question and then move that same leader behind the shield for possible use in the battle.
• Zoal copies the leader disc's value, without skill or Kwisatz Haderach additions.
• Tleilaxu taking a foreign Ghola does not draw a new skill; the revival draw belongs only to a faction reviving its own leader.
• A Richese Smuggler still supplies its extra free force with a No-Field shipment if the destination is empty.
• Spice Banker triggers when another player pays at least 4 spice to the Bank during Revival.
• A Traitor obtained by Tleilaxu through Rihani counts as a Face Dancer and may replace only an unrevealed Face Dancer.

Material boundaries not settled by the sources

These questions should remain explicit rather than be answered by a generic card framework:

1. Captured-card replacement — resolved 13 October 2026. The rules say a captured leader keeps the skill, while revival permits a draw when a faction “has no” skill card. The user selected the strict reading: the original faction still counts as having the captured card, so reviving another leader yields no replacement draw and no second assignment. See the ruling.
2. Spice Banker escrow: the gained spice waits in front of the shield until Mentat Pause. The sources do not say where it goes if the skilled leader dies or is captured before collection, nor whether capture transfers that waiting spice.
3. Smuggler timing: the face says to collect when plans are revealed, while the common rule and designer explanation require the skilled leader to survive the battle. A digital implementation needs a pending receipt or an equivalent post-resolution settlement; the source does not describe rollback of already collected spice.
4. Mentat empty-hand case: an opponent lacking the named weapon must show a different Treachery Card, but no instruction covers a hand with no other card to reveal. Later death also cannot undo information already disclosed before plans.
5. Diplomat strength and sequence: the card does not specify whether its retreat cap uses printed disc value or all surviving modifiers, or place the retreat precisely among weapon resolution, leader death and ordinary loser force removal.
6. Multiple timing opportunities: once-per-phase economic triggers and skill-before-faction ordering are clear individually. The sources give no priority protocol for simultaneous optional skills, payments and faction reactions.

Planetologist retains ordinary movement legality. Its +1 branch alone states a maximum of 3; the two-origin branch instead requires a shared destination. The designer expressly presents the latter as useful to Fremen, but does not publish a general stacking order for every expansion movement modifier (designer example, 19:13).

Bounded Diplomat retreat interpretation

A 27 September 2026 online check of the publisher's CHOAM & Richese rulebook, the designer's walkthrough and the independent Landsraad tournament reference did not establish a publisher/designer priority ruling for modified strength or the precise casualty order. The publisher's old PDF URL currently redirects to its store; the sourced printed-card paraphrase above remains the authority. For the playable standalone Leader Skills profile, use the selected disc's printed value (Zoal copies the opposing disc), not battle bonuses. Resolve weapons and leader survival first; a surviving losing trained leader may then move up to that cap in undialed physical counters before the remaining loser forces go to the Tanks. A dead leader, traitor loss or explosion cannot retreat. This is an explicit conservative implementation interpretation, not a quoted FAQ answer. Legacy battles, other optional modules and modified-skill interactions retain their existing gates.

The 5 October standalone Ecaz Nexus/Skills coalition preserves that own-force contract: an uncanceled Ecaz lead's committed own dial is the fixed Ecaz contribution, while its ally lead's own dial is the variable remainder. Do not subtract the total combined dial from either selected faction's own force pool. The other allied army cannot use this leader's retreat. Cancellation uses the selected lead's ordinary own dial. A meaningful original Nexus-alliance regression now retreats Ecaz's2 undialed counters, rejects3, and sends only its3 committed counters plus the ally's4 counters to the Tanks. This is explicit owner-pool composition, not a new combined-skill FAQ.

20 September Smuggler follow-up

A bounded renewed check of the GF9 CHOAM & Richese rules/Q&A, the core FAQ, Future Pastimes expansion page and Jack Reda walkthrough found no ruling defining Smuggler's leader strength with Kwisatz, another face-up trainer or Stunner. The walkthrough at 12:19–12:46 repeats reveal timing and survival with an unmodified strength-five example. It does not settle those modifiers. A user question now asks whether to keep those combinations gated, use printed/copied disc value, or include leader bonuses with a stunned leader counted as zero. No answer is assumed; this is not a publisher ruling.

The prior pending-receipt contract remains viable: bind the original battle, controller, leader and spice pile at reveal, then transfer only after survival is known. The printed card has no victory requirement; the designer's winning example does not add one. A captive's lower effect belongs to its controller. Resolving this reveal-time collection logically before Sandmaster's after-win addition is an explicit timing inference. A drained pile leaves no existing spice for Sandmaster to augment. Multiple-pile allocation remains unresolved. Pending spice is not spendable personal custody; this provisional timing must remain explicit in the connected unmodified collection prototype. Modified plans, other modules and multiple positive piles remain gated while their answers and integration wait.

Implementation readiness contract

A bounded prototype can now use the exact fourteen-card inventory, modified setup order, public assignment, battle conceal/reveal custody, death return, own-leader revival draw, named card-role checks, eight direct strength modifiers, the settled Q&A interactions and saved pending choices. Every human action needs the same legal AI route, and private Mentat/Rihani information must remain seat-scoped across save and recovery.

Keep the five remaining unresolved boundaries above gated or represented as explicit pending decisions. In particular, do not pay Smuggler spice irreversibly at plan reveal, transfer Spice Banker escrow on capture, or issue a replacement skill while the original card is captured. This source contract supports the bounded runtime prototype; it is not evidence that the optional module can be enabled publicly.

Smuggler modifier policy — 17 October 2026

The older numerical question remains unanswered. Under the later standing choose-recommended instruction, prototype the reveal-time cap as copied/printed disc value plus existing declared Leader Skill bonuses and Kwisatz +2. Only the surviving controller collects, and an actual resolved zero-strength weapon effect voids collection. This is a provisional interpretation, not a new FAQ. The supplied Advanced physical p21 states skill survival and played-card-role rules; physical p40 permits KH after the seventh actual loss. Neither passage supplies a specific Smuggler modifier calculation.

The old question named Stunner. The canonical base Stunner is a projectile weapon; the existing zero-strength effect is Artillery Strike. Use the actual shared weapon resolution, not either card's name: a sole own Traitor bypasses Artillery, while a surviving shielded leader is still zeroed in an ordinary Artillery result. No base weapon or bounty rule changes. See collection timing and policy.
