Weapon (greataxe), rare (requires attunement)
This axe doubles as a magical spade, allowing you to excavate twice as much with it as a normal shovel. You gain a +1 bonus to attack and damage rolls made with this magic weapon, or +2 if the target is undead. When you reduce a creature to 0 hit points with this weapon, it can't gain the benefit of any effect that would allow it to remain at 1 hit point or otherwise prevent it from dropping to 0 hit points.
Whenever you slay a humanoid with this axe, you can choose to cause its corpse to be immediately and magically buried beneath 5 feet of earth (provided it was on soil when slain). At the end of your next turn, that creature's corpse resurfaces from the earth as a zombie under your control, unless you already have two zombies under your control. Zombies created in this way take their turn as a group immediately after you. They obey your verbal commands (no action required). If you issue no commands, each zombie only defends itself against hostile creatures. Once given a command, the zombie continues to follow it until its task is complete or until you issue a new command.
Each time you create a zombie in this way, roll a d6. On a 1, the zombies no longer obey your commands and are hostile towards you and your companions; the zombies also become hostile if you're reduced to 0 hit points. Otherwise, a zombie remains for up to 8 hours, at which point it becomes a normal corpse again.
The spade that buried, now unearths.
The hand that fell, now raises.
The foe that fought, now serves.
