Axe Of Exact Zero

This 6 ½ ft long single-headed Greataxe is a family heirloom that has been passed down through generation after generation of berserkers and has now landed in your care, the adamantine and steel blade is of a bluish green color with ornate patterns engraved along its edges. On the right side of the axe head, the words “Teck Su Zero” are engraved in a beautiful flowing script, and on its left side, the words “Enmel Su Zero” are engraved in much the same way. The shape of the blade is almost rectangular and sticks out from the handle on two ornate arms fashioned to look like wings. The handle is made of ironwood and has been polished into a mirror sheen; such is the design of this weapon that one might mistake it for a flag or banner when at a distance. The pommel of the axe is in the shape of a ring encircling an enraged seraphim, this carving is unable to be mimicked by mortal means which allows the pommel to act as a mark of authenticity. 

When being wielded by a barbarian, The Axe of Exact Zero counts as a magical weapon with a +1 bonus equal to the maximum number of rages the barbarian currently has and uses 2d6 instead of 1d12 as its damage dice. If a barbarian rolls a critical hit with The Axe of Exact Zero while they are raging, the attack inflicts an extra 1d4 force damage per half the maximum number of rages the barbarian currently has rounding up. this damage die increases to a d6 at level 12, a d8 at level 17 and becomes infinite at level 20. 

Proficiency with a Greataxe allows you to add your proficiency bonus to the attack roll for any attack you make with it.
