Axe of Xander

This is a sentient, lawful neutral +1 greataxe. It has hearing and normal vision out to a range of 120 feet. When you hit one of those creatures with this weapon, it deals an extra 3d6 force damage. It also transmits a tremendous sense of satisfaction and wellbeing to its user when it kills a giant or titan. You may heal 1d6 Hit Points when this happens.
