Bayle, The Dreaded Camera.
This is my 3rd Shadow of the Erdtree playthrough where I clean through rememberance bosses like it's your average ng+1 Limgrave experience just to get eternally fucked by Bayle and to lesser extent, Sennesax.
I think I own Decaying Ekzykes an apology. Stuck at Bayle for longer than freaking Radahn.
A limited lock on that specifically fucks with melee build? Check.
Omnipresent hitboxes? Check
Peak fuckery cam that doesn't zoom away (general thing but specifically for that boss that can't be melee'd easily?)? Check
I won't deny Bayle is thematically amazing, but the targeting completely ruins all his fun moveset.
