Executioner's Axe

A blood stained axe appears above a creature within range and attempts to lop off its head. Make a Melee spell attack against the target. On a hit, the target takes 10d8 magical slashing damage immediately.

- If you roll between a 18-20 on the spell attack roll, that target takes an extra 4d8 magical slashing damage and you can choose to lop 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 additional 4d8 magical slashing damage from the hit.

- If you roll a between a 15-17 on the spell attack roll, that target takes an 2d8 magical slashing damage and you can choose to lop off one of the target's limbs, with the effect of such loss determined by the GM. If the creature has no limb to sever, you lop off a portion of its body instead.
