a non-demon creature ends their turn in area D3, or a demon in area D3 issues a command to the Witchbole's Heart to awaken
A distorted arboreal's face forms on the side of the Witchbole's Heart and issues a horrific shriek that sounds as if it were issued through an immense throat made of grinding wood. All non-demon creatures in area D3 or within 30 feet of any entrance to area D3 take 10d6 spirit damage (DC 41 basic Will save) as their own souls twist and writhe in pain. The trap then rolls initiative.

No multiple attack penalty
(3 actions) The Witchbole's Heart forms several long, thin, spiky limbs tipped with poisonous talons. On each of its actions, it attempts to Strike one non-demon creature in reach of the central sphere. The Witchbole's Heart does can't attempt to Strike a single target more than once per round.
The Witchbole's Heart deactivates and resets automatically 1 minute after no targets remain.
