Just wanted to let you know Zadum, the fungus beetle boss could use some nerfing; i just fought him post skeletron, literally after killing him i ported back and summoned him, he is practically impossible to kill without explosives to stop all his mobs. He has invincibility phases that last until you kill all his adds, correct? because i had to grab gear from my hardmode world to kill him; a mythical shadowhex doll to be precise. nothing pre-hardmode has the...aoe? to kill all his adds and him it seems.
I think just slowing him down would suffice quite a bit, he is quite literally undodgeable when fighting him; he flies incredibly fast for an end-game pre-hardmode boss...faster even than the queen bee when she is dashing, at his average speed.
Also, he doesnt despawn when you die. Died 3 times in the fight, he starts to dash even FASTER, back and forth across the screen and well off it, and he followed me back to my home each time. (had the time to run to the nurse atleast, so he didnt get the chance to spawn camp me)
