Ars 'n Spells

[1.7.0] - 2026-03-26

Critical Fixes

• Fixed SEPARATE mode dual-cost losing mana on partial failure -- If Iron's consumption fails after Ars succeeds, Ars mana is now rolled back to its pre-consumption value instead of being silently lost
• Fixed applySilentHealthLoss killing the player in safe mode -- Health floor changed from 0.0 to 1.0, preventing unintended death when LP is insufficient and death penalty is disabled
• Fixed hardcoded Blasphemy LP minimum ignoring config -- Blasphemy-discounted LP costs now respect the ars_lp_minimum_cost config instead of a hardcoded 100

High-Priority Fixes

• Removed Thread.sleep(100) from mod loading thread -- Ritual and compat initialization now deferred to ModConfigEvent.Loading instead of blocking the FML work queue
• Switched pending cost TTL to game ticks -- VirtueRingHandler and CursedRingHandler no longer use wall-clock time; costs expire after 100 game ticks (5 seconds at 20 TPS) instead of 5000ms, preventing free casts under server lag
• Fixed double event firing -- Removed 8 redundant explicit .register() calls for handlers already auto-registered via @Mod.EventBusSubscriber

Bug Fixes

• Fixed MixinManaCapability.setMana API contract violation -- setMana() now returns the requested amount instead of Iron's internal mana value
• Fixed ResonanceManager memory leak -- Cache now cleans up offline players every 60 seconds and clears all entries on server stop
• Fixed potion effect detection using fragile string matching -- Ars potion effects are now detected by registry ResourceLocation instead of matching substrings in description keys
• Fixed SLF4J format string bug -- {:.1f} (Python-style) replaced with proper String.format("%.1f", value) in EquipmentIntegration
• Fixed aura regen float precision drift -- Accumulator now uses modulo instead of subtraction to prevent IEEE 754 errors over long sessions
• Fixed cooldown namespace keys being constructed but never used -- Removed dead namespacedKey variable assignments from UnifiedCooldownManager
• Fixed AffinityData lost on death -- Added PlayerEvent.Clone handler to persist affinity levels across death/respawn
• Fixed CrossCastContext entries never cleaned up on disconnect -- Added logout handler to clear stale entries

Balance Changes

• Spell scaling changed from multiplicative to additive -- Iron's base spell power and elemental spell power bonuses are now added instead of multiplied, preventing exponential stacking. New configurable spell_power_cap (default 3.0) provides a hard limit
• Blasphemy discounts now independently configurable per resource type -- New blasphemy_lp_discount and blasphemy_aura_discount configs (default 0.85) replace the old hardcoded 85% reduction, separate from the mana discount
• Source Jar regen synergy buffed -- New source_jar_synergy_multiplier (default 5.0) makes the proximity bonus meaningful (5 mana/sec instead of 1)
• Ritual of Mana Infusion now configurable -- New ritual_mana_infusion_amount config (default 500) replaces the hardcoded value

New Features

• Ring conflict notification -- Players wearing both Cursed Ring and Virtue Ring now receive a one-time action bar warning that the rings cancel each other
• New commands:
  • /ans debug -- Toggle debug mode at runtime (op 2)
  • /ans info <player> -- Display player's mana, aura, resonance, and ring status (op 2)
  • /ans mode -- Show the current mana unification mode

UX Improvements

• Expanded language file from 8 to 28 translation entries
• Replaced hardcoded formatting codes -- LP and aura messages now use Component.translatable() with ChatFormatting constants instead of raw \u00a7 section signs, enabling proper i18n support

Code Quality

• Standardized logging -- All files now use SLF4J; removed mixed Log4j usage
• Removed emoji from log messages -- Replaced with text equivalents for cross-platform console compatibility
• Removed 11 dead code files -- AffinityTracker, CooldownManager facade, BridgeHealthCheck, ConfigCache, ModLogger, FeatureManager, 4 unused addon compat classes, and duplicate ProgressionData stub

Performance

• Source Jar block scan now cached by position -- Scans only when player moves >4 blocks from last scan position; stationary players skip all 324-block scans
• hasAnyBlasphemy reduced from 13 inventory scans to 1 -- Single curio slot iteration with HashSet.contains() lookup instead of 13 separate hasCurio() calls
