I do not know if this is by design or not, but as of a couple patches ago the debuff grubs and mob respawn have been in the queen room, regardless if all 3 of the boss rooms had been previously cleared. Also, I noticed that on return after a failed run the grub Egg room still needed to be cleared and the other 2 rooms remained empty.
I discovered that the debuffing grubs cannot be resisted with a magic defense rare.
The grubs are immediate respawn and cast continuous invuln 8 and lure blade 8, which effectively nullifies a melee skill rare. Although, a melee rare stacked with a defender rare will reduce successful hits to a negligable rate.
Thank you for any input!
