Pennywise

He is a clown that will hunt you both physicaly and mentally.

You will notice him first while trying to sleep and notice that you cant because illusions of him came from your mindscape. These illusions wont deal damage and are killed with one hit.

The real pennywise will slowly walk towards you and stare at u for a while if you hit him, he will instantly start attacking, otherwise hell only attack after some time. When you stare at him too long, he will tp to u and turn invis for 1 second. When he is hit hell go invis and summon clones of himself, this has a cooldown. He will get stronger as lower hp you are and he is. After he is "killed" hell transform into his more monster variant which only can be killed in melee and is strong.

After he is completly killed, hell respawn after 2,5min and will start to follow you again.
