Wand Surge

You can squeeze more magic out of charged items.
Prerequisite: Caster level 3rd.
Benefit: You can spend an action point instead of a charge when you activate a charged spell trigger item, such as a wand or staff. To use this ability, the item must have at least one charge remaining.
Special: If two or more charges would normally be subtracted from the charged spell trigger item, then the number of charges required is reduced by one when you spend your action point.
