When you cast this spell, and as an action on each of your turns for the duration, you can command up to four undead
that you can see within range that are under your control. You give the same command to each target. You choose from one
of the following commands when you cast this spell:

Advance. Each target can use its reaction to move up to its speed.
Apprehend. Each target can use its reaction to attempt to grapple one creature within its reach. The undead can all grapple the same target or can split their grapples between different targets.
Attack. Each target can use its reaction to make one attack against a creature they can see. The undead can all attack the same target or can split their attacks between different targets.
