+### Added
+- Runiczny Pancerz can be restored with Mana: `game.hbm.runicArmor.rechargeRunicArmor(actor, points, { partial })` – 2 Many per point, capped at the armor's maximum (Amulet Osłony, Akcja). Degradation (every 5 absorbed damage) is unchanged.
+
+### Changed
+- Money converter: NBP rates come from `src/logic/nbp.ts` – one range request per currency (first table from 1 June of the campaign year), latest published rate for future years or when no table is found, 4 s timeout, offline fallback EUR = `TRADE.eurRate` (4.36), USD = 4.00.
