Features to wire: Biokinesis + Mesmerism disciplines follow-ups

[Geph]

Follow-ups from auditing the Kibbles Psion Biokinesis and Mesmerism discipline import proposals (discipline packages + Weapon Morph / Flesh Warp / Illusory Image powers).

Implemented in the audit change

• Alternate Effects tables on both disciplines already parse into spells_known (cast via psi) — Biokinesis (11 spells) and Mesmerism (12 spells).
• Uncanny Flexibility reach → new phrase rule weapon.reach.bonus (+N ft. reach, unarmed default). AI weapon_reach_modifier already worked when present.
• Bone Plating → existing unarmored AC (10 + DEX + CON).
• Bile Blast / Mutant Regeneration uses → uses.once_until_rest now accepts complete as well as finish, and longer "Once you cast it on yourself…" clauses.
• Projected Self / Rampant Illusions uses → new uses.once_regain_after_rest for "once … regaining its use / the ability to do so after a … rest".
• Imaginary Ally uses → uses.ability_modifier accepts "a number equal to your Intelligence modifier, regaining all uses…".
• Flexible Existence → spell.cast_named_at_will now matches "gain the ability to cast X at will" (no longer swallowed as a bad gain_cast_named label).
• Beast Warping / Rampant Illusions → spell.added_to_effects_list accepts both "X is/are added…" and "You add the spell X to…".
• Mutant Regeneration → regenerate (no slot) + once/long rest.
• Sprout Wings → fly speed 30 (armor gate remains descriptive).
• Flesh Warp augments already parse via the psionic-augments gate.

1. Weapon Morph / natural-weapon morph menu

Weapon Morph is a bonus-action self morph with exclusive limb options (Bone Spike, Chitinous Plating-as-shield, Flesh Club, Sinew Whip + reach, Viscera Cannon ranged + HP ammo). Needs a structured morph/option menu that can:

• Grant temporary natural weapons / shield proficiency for the duration
• End as a bonus action
• Interact with Warped Mind talents (Combined Mutation, Voracious Absorption, Spittel Cannon, Evolutionary Optimization Light property, Sprout Tentacle reach retention)

Do not phrase-wire individual morph options as permanent weapon grants.

2. Flesh Warp Mutation Die + target state

Flesh Warp grants a temporary Mutation Die (d4, spendable on check/attack/save until start of caster's next turn) and has ally CON-mod exhaustion stacking. Augments (Flexible / Muscular / Ocular / Resistant / Perfected) parse as selectable psi augments, but the Mutation Die itself and:

• Perfected die-step growth
• Muscular auto-apply without expending the die
• Ally use-cap → Exhaustion
• Malicious Warping unwilling targeting + Exploding/Exposing/Spasming modifiers
• Swollen Muscles (set target STR = your INT until next turn)
• Flexible Flesh (Flesh Warp as bonus action when self-only)

need ephemeral grant / target-state infrastructure (related to Rampage Die play-state work in #16, but this is a granted die on another creature).

3. Bile Blast and other activatable talent attacks

Bile Blast is a special Attack-action cone (Dex save, 2d6→6d6 acid by level, once short/long — uses now wire). There is no import special_attack / force_save AI mechanic path today, so the attack body stays narrative.

Also still narrative-only:

• Slime Excretion (action: escape grapple/restrain + 1-minute acid/advantage aura)
• Spongy Body (half fall damage + weapon-catch grapple)
• Expendable Flesh (limb sacrifice → damage 0 + regenerate lockout)
• Spittel Cannon / Sprout Limb / Sprout Tentacle (permanent body mutations)
• Advantageous Assault (bonus weapon attack after Illusory Image)

4. Mesmerism illusions / Projected Self engine

Illusory Image (power) correctly suppresses passive phrase detection; its advantage/disadvantage + 1d12 riders and Traumatizing/Disorienting/Enveloping/Intrusive augments are power-time only.

Larger gaps:

• Mental Projection (harmless illustrative images) — sheet reminder at most
• Projected Self full illusion (concentration, move, cast-from-illusion origin, swap-with-illusion reaction) — uses wired; body needs illusion-token / reaction tooling
• Imaginary Ally illusory double (INT-mod uses wired) — companion-like attack proxy
• Mental Broadcast (willing-only visibility for minor illusion)
• Flexible Existence / Mutation Mastery concentration-waive + indefinite duration for named spells

5. Cross-feature / concentration-waive primitives

Repeated pattern across these disciplines and #16 subclass follow-ups: "this named spell/power no longer requires concentration" and "casting-time becomes bonus action when targeting self". Needs a stable modify-ability / waive-concentration characteristic keyed by custom-ability or spell id rather than more one-off regexes.

Update (2026-07-21)

§3 Bile Blast / activatable talent attacks — partial win

Added special_attack to AI_MECHANIC_KINDS with schema fields (attackProfile, damageDice, areaShape, saveAbility, saveHalfDamage, etc.) and a parse-ai-mechanics builder so Bile Blast–style cone/save attacks can wire from mechanics[] without a named preset.

Still open in this issue:

• Weapon Morph menu / Mutation Die target state (§1–2)
• Illusion / Projected Self engine (§4)
• Concentration-waive / modify-ability primitives (§5)
• Other narrative talents listed under §3 (Slime Excretion, etc.) beyond the AI special_attack path

Target-state / form engines are in — 35ec782, prompt follow-up in 3a62a55

1. Weapon Morph — lib/character/weapon-morph.ts grants the morph as a temporary natural weapon (or shield for Chitinous Plating) that shows up among equipped weapons with its own attack line, including the Viscera Cannon HP ammo cost and Sinew Whip reach. The five options are an exclusive toggle group (WEAPON_MORPH_TOGGLES) so only one is active, and End morph clears it (END_WEAPON_MORPH_TOGGLE_ID). Still open: the Warped Mind interactions (Combined Mutation, Voracious Absorption, Spittel Cannon, Evolutionary Optimization's Light property, Sprout Tentacle reach retention).

2. Flesh Warp Mutation Die — lib/character/mutation-die.ts grants a d4 that lives in play state with the target's name (self or ally), clears at the start of your next turn, steps up for Perfected, and keeps applying to Strength without being expended for Muscular (autoApplyStrength). Ally use counts are tracked per target (fleshWarpAllyBenefitCounts) for the CON-mod cap that leads to Exhaustion. Swollen Muscles is wired via preset. Still open: Malicious Warping's unwilling targeting and its Exploding / Exposing / Spasming modifiers, and Flexible Flesh's bonus-action self-cast.

4. Mesmerism illusions — lib/character/illusion-tokens.ts plus components/character-sheet/illusion-tokens-panel.tsx spawn Projected Self and Imaginary Ally as 1-HP tokens with AC and their own reminder text (concentration, move, cast-from-illusion, swap reaction for the first; the 1d8+INT psychic attack for the second), and they can be damaged or dismissed. Mental Projection is a reminder preset. Still open: Mental Broadcast, and the Flexible Existence / Mutation Mastery concentration waive.

3. Bile Blast, Slime Excretion, and Advantageous Assault now carry presets (Bile Blast as a cone special_attack); the remaining narrative-only talents in that section are unchanged.

5. The concentration-waive / modify-named-ability primitive still does not exist — that is the main thing left here alongside the sub-bullets above.
