From d2a1b79ee3fbd65fa4a04c7ed2d92efc70aabe1e Mon Sep 17 00:00:00 2001 From: prosolis <5590409+prosolis@users.noreply.github.com> Date: Fri, 8 May 2026 12:29:17 -0700 Subject: [PATCH] Adv 2.0 D&D Phase 11 D1e: zone combat + trap + boss resolution MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Wires real combat into !zone advance. Each room now resolves through its own path: Entry is pure flavor, Exploration spawns a SpawnWeight- biased non-elite from the zone roster, Elite filters to elite-flagged entries, Trap nicks 8–20% MaxHP scaled by tier (KO-protected), Boss runs the bestiary entry from zone.Boss with the zone Loot table on victory. Combat reuses the existing dungeonCombatPhases pipeline with the player's full D&D layer (class/race/subclass passives, equipment, HP scaling, armed abilities, pending casts) and persists HP, subclass state, and CR-weighted XP after each kill. Mood event triggers fold in: nat-20s/nat-1s scanned from CombatResult events apply +3/-2 deltas, player_death applies -5 + abandons the run, zone_complete (already wired in D1d) lands when the boss falls. Loot drops materialize into adventure_inventory with coin patterns ("coins_2d10x5") expanded into rolled gold-pouch treasure rows and named items rendered as tier-scaled placeholder treasure (real equipment-registry wiring is a later content phase). Updates the D1d mood-on-completion test to drive the persistence layer directly, since real combat against the L1 Goblin Warrens roster is non-deterministic.
