Evocation L7 Empowered Evocation adds INT mod (min +1) to Mage evocation
spell damage. Abjuration L5 Arcane Ward grants a 2×level HP buffer
absorbed before player HP, +prof at L7. Necromancy L5 Grim Harvest heals
2× spell level on spell-kill (3× necrotic) via post-combat hook.
Sculpt Spells / Potent Cantrip / Inured to Undeath skipped — no allies,
save-half is already uniform, and no necrotic enemy damage to resist.

Battle Master:
- New "superiority" resource pool (4/long-rest at L5), provisioned via
initSubclassResources at !subclass selection.
- Three armed maneuvers fueled by superiority dice:
* Precision Attack — +d8 (≈+4) to first attack roll
* Tripping Attack — enemy skips first attack (reuses Phase 9
SpellEnemySkipFirst)
* Rally — +(d8 + CHA) HealItem at <50% HP
- L7 Know Your Enemy proxied as +1 AttackBonus passive.
Assassin:
- L5 Assassinate: AssassinateAdvantage (re-roll first miss, take better
of two d20s) + AssassinateBonusDmg = level (5 at L5) stacked on top
of the Rogue's existing Sneak Attack auto-crit.
- L7 Impostor bumps the bonus damage by +3.
- L5 Infiltration Expertise → +5 Deception; L7 Impostor → +10.
Engine:
- CombatModifiers gains FirstAttackBonus, AssassinateAdvantage,
AssassinateBonusDmg.
- resolvePlayerAttack consumes each on the first attack only via new
combatState one-shot flags.
Tests added: 14 covering passive gating (BM L7+, Assassin L5/L7),
maneuver Apply flags, superiority pool init for BM only, !arm gating
across class/subclass for precision_attack, Deception bonus tiers,
statistical lift from FirstAttackBonus and AssassinateBonusDmg in
SimulateCombat.

First mechanical slice of the subclass system. Each subclass gets its L5
and L7 abilities wired through the existing combat engine + skill check
substrate; no new resource pools introduced.
Champion (L5/L7):
- Improved Critical: new Mods.CritThreshold lowers crit floor to nat 19+
in resolvePlayerAttack. Default 20 preserved for non-Champions.
- Remarkable Athlete: +½ proficiency bonus to STR/DEX/CON skill checks
via subclassSkillBonus, layered on raceSkillBonus.
Berserker (L5/L7):
- Rage: new !arm-able active ability gated to Berserker subclass via
DnDAbility.Subclass field. Reuses the Fighter stamina pool (3/long-rest
matches 5e's rage uses). On fire: +2 flat damage per hit, halve incoming
weapon damage, +50% damage approximation for Frenzy's bonus-attack-per-
turn (one-shot combat can't model that literally).
- Frenzy exhaustion: new exhaustion column on dnd_character; incremented
by persistDnDPostCombatSubclass after any rage'd combat. Decremented by
one per long rest.
- Mindless Rage: documented; charm/frighten conditions don't exist in the
combat engine yet, so no functional effect until P11 zone bosses land.
Thief (L5/L7):
- Sleight of Hand added to dndSkillTable.
- Fast Hands: +5 to Sleight of Hand checks via subclassSkillBonus.
- Supreme Sneak: advantage on Stealth (best of two d20s) via new
subclassSkillAdvantage hook in performSkillCheck. 5e's half-speed gate
dropped — we don't track movement speed.
Plumbing:
- applySubclassPassives layered after applyClassPassives in both arena
and dungeon combat bridges.
- DnDAbility.Subclass enables per-subclass gating; characterActiveAbilities
filters !arm and !abilities lists by both class and subclass.
- Existing !respec full-wipe also clears Exhaustion.
Tests: Champion CritThreshold gating across L4/L5/no-subclass; rage Apply
flag-set; rage probabilistic win-rate lift vs tougher enemy; exhaustion
increment only on raged combats; long-rest decrement; Champion bonus on
STR/DEX/CON only and only at L7+; Thief Fast Hands SoH-only; Thief
Supreme Sneak L7+ Stealth-only; statistical advantage roll lifts Thief
stealth average by ≥2 vs plain Rogue; !arm rage subclass gating; schema
roundtrip; characterActiveAbilities visibility.
