I want a warning from mana from life flasks

It would be great if the game didn't allow you to KILL YOURSELF with these flasks with chaos inoculation on.

I wasted three high level waystones before I figured out what was killing me.

Thanks for putting in measures to stop this.... I woulda preferred the flask did NOTHING but sure, go ahead and kill me and piss away hours of XP. Fantastic game design. Really wants to make me keep playing....
