@@ -5,6 +5,12 @@ 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).
 
+## [1.5.2] - 2026-10-26
+
+### Fixed
+- A character with the discipline Magia Sakralna - Egzorcyzmy (`sacredExorcism`) is now treated as a Sacred Magic caster in the spell discipline gate. Before, it only matched its own id, so exorcists failed the requirement for Sacred spells. The match is one-way: a plain Sacred mage is not an exorcist.
+- The "new round" chat message and README no longer claim that Mana is reset. Mana is a daily pool in the vault and has not been reset per round since 1.3.x; the message now says which counters really reset.
+

 - **TS d6 dice pool roller** (`HbmTSRoll`) - `1` auto-fail, `6` auto-success, configurable Threshold (T) and required Successes (Y), plus T-step / Y-step modifiers driven by Active Effects.
 - **Derived stats** - `health.max = 3 × (body + mind + soul)`, `zeal.max = ceil(soul/2)`, initiative pool, mana table lookup (Magic Power Level 0–X), blood pool (`body + soul`), elixir tolerance cap (`body + 1`), insanity counter.
 - **4-layer damage model** - Magical Armor (with runic counter) → Magical Shield → Physical Armor (DR + condition) → Health. `Apply Damage` dialog with bypass flags; auto-applies `Oszołomiony` on heavy HP loss.
-- **Combat hooks** - Mana resets each round; Zeal +1 each turn; turns auto-skipped for Nieprzytomny / Obezwładniony; Podpalony ticks 1 environmental damage; Umierający prompts a Death Save.
+- **Combat hooks** - Mana is a daily pool (not reset per round; recovered by rests); Zeal +1 each turn; Immediate Action and Krew counters reset each round; turns auto-skipped for Nieprzytomny / Obezwładniony; Podpalony ticks 1 environmental damage; Umierający prompts a Death Save.
 - **Spell-cast workflow** - `validateCast()` gates on resources / race / talent / discipline / deity / group / inCombat / superspell / witch-symbol; dispatcher routes to standard / Sacred / Witch / Blood / Hekate hybrid; `rollSpellDamage()` parses formula tokens; reactive triggers (`killWithWeapon`, `targetCastsSpell`, `damageTaken`, `turnStart`).
 - **Cast dialog** - mana / zeal / blood inputs, group-caster picker, Hekate toggle, GM bypass checkboxes (superspell, non-combat block), inline validation feedback.
 - **Mechanics modules** (`game.hbm.*`) - `bloodMagic` (Self-Harm, Life Steal, talent integration), `abyssMagic` (Aspects vs Primal, Mistrz Losu penalty, `Dary Otchłani`, insanity gain), `brewing` (TS test + tolerance counter), `rest` (short / long), `trade` (founding company workflow, transactions, smuggling).
