/*
* Every 2 seconds after completing an attack do one of the following attacks:
Casts a Stone Pillar on the location of the Player: radius 350. Hits with 3 seconds delay. Becomes an solid object (Player colision) and decays after 5 seconds again.
	If the Stone pillar would hit the Stone Elemental it will move out of its range.
Shoot a Stone (bullet) in the direction of the target. 
	The Stone gets created in form of a Cone and tracks the player movement without moving for the first second. 
	Once it locks it doesnt move for another second. then it starts flying towards the player with 3x the normal Bullet speed.
Dive under earth and show up 1 second later in a random location 400-700 away from player. while emerging shoot a ring of bullets (0.5x Attack)
	(maybe emerge with 200 away from anything with colision to avoid the Elemental getting stuck? Other solutions for that are welcome aswell)
if range to player > 1200 always use 3rd attack
