Flask charges on bosses.

Find a way to recover flask charges on boss fights and for every classes by default. Not an ascendancy not a keystone not a passive not a unique not a curse. Using a flask 4-5 times then nothing for the rest of the fight is rough where there are no additional monster spawns during an encounter.

I believe there's a mechanic in the game, or a roll you can get on the bottle that it gains .x charges per second. I do agree though, having no way to regenerate your flasks during a boss fight feels rather bad.

Perhaps having each boss spawning adds which naturally (and inherently make kills on mobs regenerate flask charges instead of it being something that has to be rolled on the flask) regenerate flask charges provided you can avoid the bosses attacks may be helpful.

Thx and God bless
