Throws a huge rock that explodes over 20 m and splits into 5 smaller ones. It knocks you far back.
How to dodge it: Move sideways and stay away from edges: it can knock you off the map.
Throws a slow orb that goes through walls and pulls you in for 10 s.
How to dodge it: Run the other way and do not fight near cliffs.
Only below 50% health: creates a sun above him that heats everything within 200 m for 14 s; the longer you stay in the light, the more it burns.
How to dodge it: Get into the shade: block the sun (the one above, not the giant) with a rock or a wall.
When it is the teleporter boss, each green item it drops has a 15% chance to be its boss item instead: Planula.
Planula
Every hit you take heals you 15. Great against lots of small hits. Each extra one, 15 more.
Stacking: Each copy adds the same, no cap.
Watch out: It heals before the hit lands, with damage over time and falls too; not with void fog.
