Price +3 bonus
This special ability can only be placed on melee weapons. A spellstealing weapon allows its wielder to siphon protective magic from a target and transfer it to herself. When the wielder rolls a critical threat against a target, she can forgo confirming the critical hit and instead automatically learn which spells or magical effects are active upon the target. The wielder may then make a caster level check to steal her choice of one of those effects, using the spellstealing weapon’s caster level plus its enhancement bonus, against a DC of 11 + the caster level of the effect. If the check succeeds, the target immediately loses the benefits of that effect and the wielder gains the effect for 1 minute (or until the effect expires, whichever comes first). If the spellstealing weapon has a critical multiplier greater than x2, the wielder may attempt to steal one additional spell effect per additional multiple beyond x2 (two effects for x3, and so on).
