You can increase the potency of your weapon's strike by infusing it with a spell.
Prerequisite(s): Spellcasting, Attack Bonus +2
Benefit(s): As part of an attack, you can infuse a spell into your weapon so long as it has a casting time of a standard action or less. This spell must be an attack - if the attack is against Reflex Defense it doesn't require an additional attack, however if it is an attack against Fortitude Defense or Will Defense another attack is made against them using the character's weapon attack roll. The spell applies to the first attack the user performs.
If the weapon used is a ranged weapon, the ranged weapon's range is relied on over the spell. If the spell is a cone, radius, or otherwise not a single target attack and the weapon used is a melee weapon the weapon is used as the origin for the spell's effects. Otherwise if the weapon is a ranged weapon it uses the target of the attack (or their square) as the origin. Radius effects which catch the caster still affect him.
