Channel Divinity resource pool (2/long-rest) shared across all three
Cleric domains. One armed expression per fight, mirroring Battle Master.
Life Domain
- L5 Disciple of Life: heal spells restore +(2 + slot level) extra HP
(lifeDomainHealBonus, hooked into resolveHealOutOfCombat).
- L5 Preserve Life: Channel Divinity heal — sets HealItem to 5×Cleric
level, capped at HPMax/2; fires when player drops below 50%.
- L7 Blessed Healer skipped — no allies in 1v1 combat to "heal an ally".
War Domain
- L5 War Priest passive: +1 attack bonus + 0.15 DamageBonus, proxy for
bonus-action extra-attack throughput one-shot combat can't model
discretely.
- L5 Guided Strike: Channel Divinity → +10 to first attack roll
(FirstAttackBonus).
- L7 War God's Blessing skipped — ally reaction, no allies.
Trickery Domain
- L5 Invoke Duplicity: Channel Divinity → AssassinateAdvantage (reroll
first miss) + 0.10 DamageBonus, proxy for "advantage on attacks vs.
creatures adjacent to the duplicate".
- L7 Cloak of Shadows passive: +2 SporeCloud rounds (15% enemy miss)
proxy for the brief invisibility window.
- L5 Blessing of the Trickster skipped — non-combat Stealth flavor.

Slots into the Phase 9 spell pipeline so an L5+ Rogue who picks Arcane
Trickster becomes a third-caster on the Mage list, INT-based.
- isSpellcaster(c) gate: full casters by class plus AT Rogue at L5+.
!cast / !spells now consult this; the cast class-gate also accepts
Mage-tagged spells when the player is an AT Rogue.
- subclassSpellSlots() / slotsForCharacter() / setSpellSlotsForCharacter()
layer subclass slots on top of the class baseline. AT pool: 3 L1 at
L5–6, 4 L1 + 2 L2 at L7+, +2 L3 at L13+ (third-caster table).
- spellcastingMod returns INT for AT Rogue.
- L7 Magical Ambush proxy: spellSaveDC bumps +2 once Rogue+AT hits L7,
standing in for "targets have disadvantage when casting from hidden"
since the one-shot combat layer doesn't model hidden state.
- ensureSpellsForCharacter bootstraps a Mage-list starter spellbook
(minor_illusion, shocking_grasp, magic_missile, shield, sleep at L5;
mirror_image + misty_step at L7+; hypnotic_pattern at L13+) and
refreshes the slot pool on level/subclass change.
- applySubclassChoice runs ensureSpellsForCharacter for AT so the
spellbook is provisioned at selection time (idempotent).
- !cast clamps upcasts to highestAvailableSlotForChar when AT, since
third-caster's slot ceiling lags behind the spell list.
Tests added: AT spellcaster gate (L5 cutoff, non-AT Rogue rejected), INT
mod, subclass slot pool by tier, L7 ambush DC bump, ensureSpells default
list (all on Mage list, slots correct), end-to-end !cast queues
magic_missile for AT Rogue, !cast rejects plain Thief Rogue.

- Enforce per-level Mage known-spell cap in handleSpellsLearn; surface
spellbook budget in renderSpellsList.
- Mage level-up DM now nudges with "Spells available to learn: N" via
extracted buildLevelUpMessage.
- Extract halveSavedDamage and enemySpellSaveMod for clarity; document
