Quiver of Energy

Constructed of supple leather, this quiver is festooned with arcane symbols.

A quiver of energy can hold up to 20 arrows or bolts. Each quiver imbues arrows or bolts drawn from it with a particular type of energy (acid, cold, electricity, or fire), indicated by the arcane symbols it bears. Such projectiles, if left within the quiver for at least 1 round before being drawn, deal an extra 1d6 points of the appropriate type of damage.

The projectile loses this extra damage after it is used in an attack, or 1 round after it is drawn (whichever comes first).

Prerequisites: Craft Wondrous Item, energy missile {CP 88} or the appropriate spell from the following: lightning bolt, ice storm, fireball, or acid arrow.

Cost to Create: 7,500 gp, 600 XP, 15 days.
