Crowbell (Glitch Unkillable)

If you do too much dmg to Crowbell he can forever become invulnerable and never go to his next phase.

This needs to be fixed.
It's bad enough you added all these phases where they just become invulnerable while they just continue to attack you while the only thing you are allowed to do is wait for whatever timer so they go to the next phase.

This is dumb and needs to be removed.
Invulnerable while they phase change is FINE, if that's what you want but allowing the fight to keep going but you can't do anything is ridiculous and why stuff like this happens.
