From b7afe7a43489ee60ed28b20d7a3f35e5f48b55cf Mon Sep 17 00:00:00 2001 From: n8n-gitea Date: Sat, 13 Jun 2026 13:42:05 +0200 Subject: [PATCH] feat: Implement Invocation System for Invoker attunement MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements the full Invocation System as per spec §13 with all 22 acceptance criteria: - Invocation charge meter with passive fill and active drain - Auto-activation when charge reaches 100 with living enemies - Guardian selection by elemental bonus × tierMultiplier scoring - Spell selection from guardian's full element spellbook (not limited to learned) - Step-down to affordable spells, auto-end when none affordable - Charge drain during invocation with spell cost and discipline scaling - Pact affinity cast speed bonus (diminishing returns, max 50%) - guardian-invocation discipline with 4 perks (efficiency/speed/sustain/mastery) - Cost multiplier (base 0.1, min 0.05) and drain multiplier (base 1.0, min 0.7) - Signal recharged on spire exit and reset on descent - Invocation Panel UI in SpireCombatPage with charge meter and status - Compact invocation status indicator in SpireCombatControls Files changed: - data/disciplines/invoker.ts: Added guardian-invocation discipline definition - effects/discipline-effects.ts: Added invocationChargeRateBonus, drainRateMultiplier, invocationCostReduction stat keys - utils/invocation-utils.ts: NEW - All invocation utility functions (guardian selection, spell selection, charge rate, cost/drain multipliers) - stores/combat-state.types.ts: Added invocationCharge and activeInvocation fields - stores/combatStore.ts: Added invocation state defaults, resetInvocationState action, partialize, spire exit reset - stores/combat-invocation.ts: NEW - Extracted invocation tick processing (charge fill/drain, casting, auto-activate/end) - stores/combat-melee.ts: NEW - Extracted melee combat processing (keeps combat-actions.ts under 400 lines) - stores/combat-actions.ts: Integrated invocation and melee modules - __tests__/invocation-system.test.ts: NEW - 39 comprehensive tests - SpireCombatPage.tsx: Added InvocationPanel between SpireHeader and RoomDisplay - SpireCombatControls.tsx: Added compact invocation status indicator All 1235 tests pass (including 39 new invocation tests). --- docs/circular-deps.txt | 2 +- docs/dependency-graph.json | 2 +- docs/project-structure.txt | 4 + .../SpireCombatPage/SpireCombatControls.tsx | 33 +- .../tabs/SpireCombatPage/SpireCombatPage.tsx | 84 ++++- .../game/__tests__/invocation-system.test.ts | 357 ++++++++++++++++++ src/lib/game/data/disciplines/invoker.ts | 50 +++ src/lib/game/effects/discipline-effects.ts | 3 + src/lib/game/stores/combat-actions.ts | 83 ++-- src/lib/game/stores/combat-invocation.ts | 266 +++++++++++++ src/lib/game/stores/combat-melee.ts | 107 ++++++ src/lib/game/stores/combat-state.types.ts | 8 + src/lib/game/stores/combatStore.ts | 12 + src/lib/game/utils/invocation-utils.ts | 213 +++++++++++ 14 files changed, 1165 insertions(+), 59 deletions(-) create mode 100644 src/lib/game/__tests__/invocation-system.test.ts create mode 100644 src/lib/game/stores/combat-invocation.ts create mode 100644 src/lib/game/stores/combat-melee.ts create mode 100644 src/lib/game/utils/invocation-utils.ts diff --git a/docs/circular-deps.txt b/docs/circular-deps.txt index ee4de90..fc7bf2e 100644 --- a/docs/circular-deps.txt +++ b/docs/circular-deps.txt @@ -1,5 +1,5 @@ # Circular Dependencies -Generated: 2026-06-12T17:03:20.112Z +Generated: 2026-06-13T11:02:39.214Z Found: 4 circular chain(s) — these MUST be fixed before modifying involved files. 1. 1) data/guardian-encounters.ts > data/guardian-procedural.ts diff --git a/docs/dependency-graph.json b/docs/dependency-graph.json index 2f7c52d..1218209 100644 --- a/docs/dependency-graph.json +++ b/docs/dependency-graph.json @@ -1,6 +1,6 @@ { "_meta": { - "generated": "2026-06-12T17:03:17.869Z", + "generated": "2026-06-13T11:02:37.078Z", "description": "Import dependency graph for src/lib/game.
