Grimlore's Grimoire
3-level Necromancy
You touch a creature and utter an ancient curse. The target
must succeed on a Strength saving throw or take 2d8
necrotic damage and become restrained as spectral
wrappings begin to tighten around its body. Until the spell
ends, as an action on each of your turns, you can cause the
target to take an additional 2d8 necrotic damage every round
after the spell was initially cast. The target can use its action
to make a Strength saving throw, breaking the spectral
wrappings and ending the spell.
A creature that dies while under the effect of this spell
becomes a mummy that is friendly to you and your
companions for the remaining duration. Roll initiative for the
mummy, which has its own turns. It obeys any verbal
commands that you issue to it (no action required by you). If
you don’t issue any commands to the mummy, it defends itself
from hostile creatures but otherwise takes no actions. Once
the duration is reached, the mummy dies and turns to ash.
If your concentration is broken, the mummy doesn’t die.
Instead, you lose control of the mummy, it becomes hostile
toward you and your companions, and will attack. An
uncontrolled mummy can’t be dismissed by you, and it turns
to ash 10 minutes after the spell was initially cast. The DM
has the mummy's statistics.
