@ScottDeWar_jr has chosen to have Vinccenzo cast the spell Dolorous Blow (SC p. 70) on Lil' Vinny and then move 5-ft. to block the front door leading out the shop, which is wide open (it opens outward). It lasts 1 minute/level, so for Vinny that is 6 minutes.
For the duration of the spell, the weapon's threat range is doubled, and its critical threats automatically confirm, so every threat is a critical hit. The latter effect does not apply to any weapon that already has a magical effect related to critical hits.
Multiple effects that increase a weapon's threat range (such as this spell and the Improved Critical feat) don't stack. You can't cast this spell on a natural weapon, such as a claw.
