Crypt Keeper Glaive

Alter: You gain a +3 bonus to attack and damage rolls made with this magic weapon.

When you use the glaive to reduce a Small or larger creature that is hostile toward you to 0 HP, roll a d10. You gain temporary HP equal to the number you roll.

In addition, the glaive's blade begins to glow with a sickly green haze whenever you gain temporary HP in this way. While glowing, the first successful melee attack you make with the glaive deals an extra necrotic damage equal to the number of temporary HP you gained. Once you deal this bonus damage, the haze fades.

The haze and temporary HP are lost after 1 minute.

Undead creatures killed by this weapon cannot be raised from the dead again.

6 feet under. The first time on your turn that you land a successful melee attack with this weapon against a creature that is prone, the weapon's damage die is maximized.
