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.
