You can focus the raw magical energy of a wand or staff into a beam of energy.
Prerequisite: Use Magic Device 4 ranks.
Benefit: When using a spell trigger device, such as a wand or staff, you can expend a charge from the device and produce a ray of magical energy that you can fire at a single target within 60 feet. With a successful ranged touch attack, the ray deals damage based on the level of the spell normally produced by the magic item, according to the table below.
For example, a charge from a wand of cure moderate wounds could be used to deal 3d6 points of damage to a target. This attack benefits from Weapon Focus (ranged spells) and similar feats and effects. The ray is treated as a spell of the same level as the spell normally produced by the magic item. Spell resistance applies to the damage, using the caster level of the spell trigger item.
