Boss immune to blind ?

Are map boss immune to blind ? Im considering adding this effect to my totem but if its only works on trash it would be useless.

I use Stibnite flask or some other blind mechanics with most of my builds and I cant remember Ive ever encountered a blind immune boss.

Blind works on bosses but if they use spell damage, which most of them do, then blind will not help you with that. The mechanics on blind are similar to evasion, it just makes them less likely to hit you. They are rolled separately so a high evasion with blind can make your chance to mitigate an attack very high.

if they use spell damage hits and you use shields you can swap a kongming's for a 50% dmg redux combined with fortify with added benefit when you got other reductions :)
