From 76f814c0c9e96bd2e5a41dbbd73e056cb744ec5e Mon Sep 17 00:00:00 2001 From: prosolis <5590409+prosolis@users.noreply.github.com> Date: Thu, 14 May 2026 20:15:16 -0700 Subject: [PATCH] =?UTF-8?q?D&D:=20class-balance=20Phase=202=20=E2=80=94=20?= =?UTF-8?q?passive=20+=20L5=20subclass=20tuning=20+=20in-tier=20parity=20a?= =?UTF-8?q?ssertion?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The Phase 1 per-class-mean summary was hiding the truth — most cells are floor/ceiling-saturated (L10+ pinned at 1.0, L1-4 caster cells at high tier pinned at 0.0), so means barely budge when you tune passives. Added a per-(level, tier) cross-class spread diagnostic to the matrix log, then tuned with the levers from doc §6 in priority order: 1. Class passives (dnd_passives.go) — caster trailers (Bard, Mage, Warlock, Sorcerer) gained level + casting-stat-scaled FlatDmgStart bursts so the L1-4 chassis isn't a quarterstaff + one weak spell against a T2-T3 monster; small DamageBonus riders (Mage/Bard/ Sorcerer/Rogue +5%, Warlock 10→12%) and +1 attack for Bard/Warlock close the steady-DPS gap. Added clampNonNeg so ability-mod-scaled additions never go negative on sub-10-stat sheets. 2. Subclass L5 tiers (dnd_subclass_combat.go) — the three Sorcerer L5 picks (Wild/Storm/Draconic) and Warlock Great Old One were defense- only or near-inert pre-tune; each gained a small bite (DamageBonus +0.10, or a FlatDmgStart burst for Storm) so the L5 chassis can press through a T4 monster. Parity band locked in TestClassBalance_Phase1_FullMatrix: cross-class spread ≤ 35pp on the in-tier diagonal — (level, tier) cells where the level is appropriate for the tier (T1: L1-4, T2: L3-7, T3: L5-10, T4: L7-15, T5: L10-20). Off-tier cells (L1 mage at T3 dungeon etc.) are still logged but not asserted: those are level-vs-tier mismatches and casters at L1-4 can't muscle through a T3 monster on a single L1-slot spell the way martials muscle through with weapon dice. Worst in-tier cell after tuning: ~26pp at L3/T2. The 35pp band gives ~9pp Monte-Carlo headroom over the worst signal at 200 trials/cell. TestApplyClassPassives expectations updated to match the new passives. Phase 0 spike still green, full plugin suite (-short) clean. --- gogobee_class_balance.md | 35 ++++++- internal/plugin/dnd_class_balance_test.go | 118 +++++++++++++++++++++- internal/plugin/dnd_passives.go | 58 +++++++++-- internal/plugin/dnd_subclass_combat.go | 16 +++ internal/plugin/dnd_xp_test.go | 17 ++-- 5 files changed, 224 insertions(+), 20 deletions(-) diff --git a/gogobee_class_balance.md b/gogobee_class_balance.md index 5d0b053..b61e99a 100644 --- a/gogobee_class_balance.md +++ b/gogobee_class_balance.md @@ -95,12 +95,37 @@ HP-remaining, and near-death-rate are logged as diagnostics, not asserted. logs the cells plus per-class tier means and ranges.
