" Defeat Magaera with 10 active Molten Skeletons "

Can anyone tell me how?
She maybe spawns 6 Skeletons at once and kills them after a few seconds with her firestorm skill ô0

Am i missing something?

She doesnt kill them at all. They have very low hp and only last so long.

Take the map and alt spam until you get "monsters gain frenzy charge on hit'.
Then let her build frenzy charges. she will start to spam summon them. Once there are 10+, just single target her down. NO AOE.

Thank u! Got it, after a lot of tries ^^" annoying
