โ๏ธ๐ Boss Mechanics ++ ๐โ๏ธ
Bosses should feel like bosses. ๐ฉธ
Boss Mechanics ++ shifts more of the gameโs difficulty away from elites, in favour of harder boss encounters. The goal is to let you take bigger risks during the run, build a stronger deck, without which you will definitely lose.
You should not be able to breeze through bosses just because you entered the room with enough HP. Bosses are now more about preparing the right deck for the fight, and ending the encounter before the pressure overwhelms you. โณ๐
