Grimlore's Grimoire
9-level Necromancy
You create a shadowy pool centered on a flat surface that you
can see within range. The pool is 30 feet in diameter and
connects your plane to the Shadowfell. A spectral hand rises
from the center of the pool and remains there for the
duration of the spell. The spectral hand does not occupy its
space.
When a creature enters the pool for the first time on a turn
or starts its turn there, the creature must succeed on a
Constitution saving throw or take 10d12 necrotic damage, or
half as much damage on a success. Any creature that is
reduced to 0 hit points while in the pool sinks to the bottom
and is immediately transported to the Plane of Shadow,
becoming trapped there.
Additionally, as a bonus action on your turn, you may
command the spectral hand to beckon a creature within 120
feet of it. The target must make a Wisdom saving throw or
have an enchantment placed upon it, causing it to approach
the spectral hand. The creature must spend its turns trying to
move as close to the spectral hand as it can, using the Dash
action.
A creature enchanted in this manner can make a Wisdom
saving throw at the end of each of its turns. If it successfully
saves three times, the enchantment ends and the creature is
immune to this effect for 24 hours. If it fails its save three
times, it becomes stunned and the enchantment ends. The
spectral hand can only enchant one target at a time in this
manner.
