An execution axe has the brutal 2 property, so when rolling damage with an execution axe, any die showing a natural roll of 1 of 2 is rerolled until it shows a natural roll of 3 or higher. It also has high crits, dealing an extra 1d12 damage at levels 1-10, 2d12 damage at levels 11-20, or 3d12 damage at level 21-30, on a critical hit. No class has proficiency with the execution axe as a class trait, but any character can become proficient by taking a Weapon Proficiency feat.
