CHANGELOG.md

@@ -5,6 +5,26 @@ All notable changes to the **HbM RPG v3** Foundry VTT system.
 The format follows [Keep a Changelog](https://keepachangelog.com/en/1.1.0/) and
 this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
 
+## [Unreleased]
+
+### Added
+- Spell cast dialog has a **Modyfikator liczby kości** (dice modifier, +/-). It changes the number of dice in the casting test for every casting mode (standard, sacred, witch, blood, prayer); the pool never drops below 0. The over-limit Nadczarowanie test uses the same modified pool. API: `CastOptions.diceModifier`, `applyDiceModifier()` in `rules.ts`.
+
+## [1.5.1] - 2026-10-22
+
+### Added
+- Weapons have wound kinds (`system.weapon.woundKinds`: `slashing` sieczne / `piercing` kłute / `blunt` obuchowe, several allowed, empty = unspecified), editable on the gear sheet as a multi-select. Matches Foundry Sync Brief §18.
+- Gear parser reads `wound` (string, comma list or YAML list; Polish or English words) from vault weapon notes. Unknown values are dropped; nothing is guessed.
+- Packs rebuilt from the current vault: Sztylet piercing+slashing, Bicz slashing, Laska blunt, bows and Włócznia piercing; generic one-/two-handed entries list all three (pick the real type per weapon).
+
+### Changed
+- `applyDamage` takes `woundKinds` (array) instead of a single kind; passive Krew applies when any is slashing or piercing. Blunt (and unarmed) never gives Krew.
+- Vault sync of 2026-10-22 needs no further logic changes: runic armour wording, Zakazana Osłona retaliation, Rozerwanie Run artifact destruction and free Immediate Action for Kradzież Życia / Złożenie w Ofierze were already covered in 1.5.0 (spell, talent and discipline text arrives through the rebuilt packs).
+
+### Notes
+- Callers of `applyDamage` still need to pass the equipped weapon's `woundKinds`.
+- Kości Losu use is now an Immediate Action that counts toward the limit (vault `Zużywanie Ładunków`); the system has no Fate-dice action code yet.
+
 ## [1.5.0] - 2026-10-20
 
 Vault answers (Foundry Sync Brief §17): blood magic and Runiczny Pancerz.
