This black silk vest is heavy with moonstone and jacinth beadwork sewn into arcane patterns on the back.Crackling with power, a vest of the master evoker intensifies arcane evocation spells you cast. Many an ambitious evoker sees gaining this vest as a rite of passage, much like casting his first magic missile or fireball, and among elite warmages (CAr 10) it serves as an unparalleled status symbol.

Three times per day, you can activate the vest to enhance the next arcane evocation spell you cast before the end of your turn. That spell deals additional damage equal to twice its spell level, and the save DC of the spell increases by 2. This damage is of the same type as normal for the spell (or, if the spell deals more than one type of damage, of any one of those types at your discretion). If the spell doesn’t normally deal damage, this use of the vest has no effect.
In addition, you can apply the effect of any sudden metamagic feat (CAr 83) you know to any evocation spell you cast from a wand or staff as if you were casting the spell yourself. Doing this requires no activation, but uses up that feat’s daily use as normal.

Prerequisites: Craft Wondrous Item, Spell Focus (evocation) or evoker, able to cast at least five evocation spells, two of which must be 5th level or higher.
Cost to Create: 5,000 gp, 400 XP, 10 days.
