Immunity mobs and respecc

So i just hit Nithalhak on Hell and found out he’s immune to my orb/fireball specc (fire frost immune ofc)

Now i did a respecc into lightning and got him down.
Only thing now, i realize i dont have any more respecs… So im stuck on a lightning only build and quite frankly, thats a pain to paly!.

Any good advice???
I know about the essences-tokens, but ive only got them from the first 2 bosses…

i fear my 81 sorceress is dead… :frowning:

If you play online trade for the rest of the essences.

If not, as lighting you should be able to solo all bosses. If you have to do diablo, use a lower resist wand for the lightning immune seal bosses or let your merc kill them.
