Sanguine Horror
Roll initiative for the elemental, which has its own turns. It obeys verbal commands from you (no action required by you). If you don’t issue any commands to the blood elemental, it defends itself but otherwise takes no actions. If your concentration is broken, the blood elemental doesn’t disappear, but you lose control of it and it becomes hostile to you and your companions. An uncontrolled blood elemental cannot be dismissed by you, and it disappears 1 hour after you summoned it.
