Magister's Staff

Made of solid silver hardened with alchemical treatments, the staff is capped with obsidian at the top and dull iron at the bottom.
Benefit: When you attune to the Magister's Staff, you must remain attuned to it until the end of the [Quest]. At the beginning of each [Quest], the Magister's staff gains 14 charges. Whenever you successfully complete an [Encounter] without falling [Dead] or [Unconscious], you gain 2 more charges. You may accumulate up to 42 total charges. Charges may be used to cast any spell you know without reducing your spells per [Scene] at the cost of 1 charge per circle of the spell you wish to cast. Once per [Scene], you may switch one spell you know for another spell of the same circle or lower. This spell must be on your casting track's spell list and the swap must be at the start of the [Scene]. When you become unattuned from the Magister's Staff, all spells known that were swapped revert to the originally swapped out spells.
