Bladethirst

For the round following the casting of this spell, any single-edged, slashing weapon is granted a +3 bonus to hit (but not to damage). The blade ignites with a fiery blue-white glow visible to all, which fades once the weapon has struck an opponent or at the end of the next round, whichever comes first. This bonus is in addition to any Strength bonus or inherent magical bonus of the item. A sword +1 provided with this spell will strike with a +4 bonus the next round, then return to being a +1 blade.
Only one bladethirst spell can be placed on an item at one time. This spell cannot be made permanent.
