Objective

Implement and verify all 10 Druid Shape Shifting Tree skills conforming to D2 v1.13c ground truth:

Werewolf (223) - Lycanthropic wolf transformation (attack speed, attack rating, stamina, life)
Lycanthropy (224) - Passive maximum life bonus & shift form duration scaling (+20s + 20s/lvl)
Werebear (228) - Ursine transformation (massive defense, enhanced physical damage, life boost)
Feral Rage (232) - Wolf-only charge-up attack granting orbiting red life-leech & run-walk speed orbs (1-3 levels)
Maul (233) - Bear-only charge-up attack building spinning green damage & stun orbs (1-5 levels)
Rabies (238) - Infectious biting poison spreading autonomously between adjacent monsters
Fire Claws (239) - Elemental beast melee strike adding immense fire damage scaled by elemental synergies
Hunger (242) - Dual life & mana leech bite/swipe at reduced weapon damage penalty (-75%)
Shock Wave (243) - Bear-only frontal conical sonic roar dealing physical damage and multi-second stun
Fury (248) - Rapid 5-hit uninterrupted feral frenzy strike sequence

Quality Standards

Isolated git worktree feat/druid-shapeshift
Zero regressions on existing test suites
0 typecheck errors
Adversarial & property stress test coverage
Strict D2 v1.13c mathematical formulas, synergy scaling, and animation timings

Milestone M23: Druid Shape Shifting Spells (10 skills) — 100% COMPLETE & VERIFIED

1. Scope & Delivered Skills

Werewolf (223): Wolf form morph/revert, base IAS diminishing returns [20, 29, 36, 42, 47, ...], base stamina, Lycanthropy form duration + max HP integration.
Lycanthropy (224): Passive duration scaling (40 + slvl * 20 s), max HP boost (50 + (slvl - 1) * 3 %).
Werebear (228): Bear form morph/revert, base defense bonus (100 + (slvl - 1) * 25 %), enhanced physical damage (50 + (slvl - 1) * 17 %), HP boost (+50%).
Feral Rage (232): Wolf-only charge-up attack, 3-stage charge orb progression, life steal (4 + 4*charge + slvl %), run/walk speed bonus (19 + (slvl-1)*2 % diminishing), attack rating bonus.
Maul (233): Bear-only charge-up attack, 5-stage charge orb progression, enhanced damage (20% + 20% * charge + (slvl-1)*13% * charge), stun duration scaling (18 + 6*charge + (slvl-1)*3 frames).
Rabies (238): Wolf-only virulent poison bite, progressive damage and poison duration scaling, Poison Creeper synergy (+18%/blvl), 4-subtile contagion spread across nearby targets every 4 frames.
Fire Claws (239): Dual-form beast attack adding massive fire melee damage with 4-way elemental synergy (+22%/blvl from Firestorm, Molten Boulder, Fissure, Volcano).
Hunger (242): Dual-form desperation bite with fixed -75% damage penalty, high life leech (slvl * 6 + 6 %) and mana leech (slvl * 6 + 6 %).
Shock Wave (243): Bear-only seismic sonic cone, area physical damage, Maul synergy (+5%/blvl), stun duration scaling (40 + (slvl - 1) * 15 frames).
Fury (248): Wolf-only uninterrupted multi-hit feral attack (min(2 + slvl - 1, 5) hits), damage & attack rating bonuses, dynamic multi-target distribution.
