>>715905817It's a special boss battle at the 50% mark of the game.
It's the only time so far performance died on me and it's specifically these moving rings of terrain (since those are actual terrain features you interact with like in the regular game, not objects, warping terrain is MUCH more costly on a game engine than just moving an instance of an object)
The battle takes place on the big rock.. ship... thingie and the entire gimmick of the battle is the boss summoning in terrain features, more details for THAT arena would therefor be counter intuitive.
