Description

Qualities
You gain a +3 bonus to attack and damage rolls made with this magic weapon. In addition, the weapon ignores resistance to slashing damage. When you attack a creature that has at least one head with this weapon and roll a 20 on the attack roll, you cut off one of the creature's heads. The creature dies if it can't survive without the lost head. A creature is immune to this effect if it is immune to slashing damage, doesn't have or need a head, has legendary actions, or the GM decides that the creature is too big for its head to be cut off with this weapon. Such a creature instead takes an extra 6d8 slashing damage from the hit.

When you hit someone with this axe, their stamina is reduced by a fourth of the amount. When you are proficient, the axe's stamina cost is halved further.

In addition, you may cast Antimagic Field once per long rest with this weapon.

Lore
St. Anastasius the Bold was a human priest who went to fight for a king because the invading armies, in his own words, were 'causing too much of a ruckus for a peaceful monk to bear'. Taking his axe that he used to chop wood in the Great Forest (now lost), Anastasius singlehandedly slew the last Magelord of Eregalia, ending the rule of magic in Western Sovenia. When the old monk died, his axe was taken to the Abbey of St. Anastasius in Morganbury, where it would only be taken to execute mages who violated the Mage Codes.
