@@LubitelRogalikov Hive Mind enrages both on the surface and outside of the corruption. The enrages just make him teleport and move faster, but if you're struggling with the speed he moves already then I'd recommend making an underground corruption arena. The vile spit can be destroyed since it's an NPC and not a projectile, but the vile clots cannot - the main reason I actually went summoner for this fight was so I could use the whip to destroy the vile spit (inferno potion sort of works, but it takes a 'hot' minute to actually destroy the spit because you have to wait for the fire tick). As for the shade rain, the best practice for that is to just (after the boss spawns it in) try and get to whichever side of the arena is more spacious, since you get more room to dodge.
@@LubitelRogalikov Adrenaline helps kill minions and deal decent damage, especially because this boss just has a stupid healthbar and all its mechanics only serve to extenuate it.
