Animate Flameskull

The flameskull is friendly to you and your companions for the duration. Roll initiative for the flameskull, 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 flameskull, it defends itself from hostile creatures but otherwise takes no actions.

If your concentration is broken, the flameskull doesn't disappear. Instead, you lose control of the flameskull, it becomes hostile toward you and your companions, and it might attack. An uncontrolled flameskull can't be dismissed by you, and it disappears 1 hour after you summoned it.
