I've done the quest line in here, & also killed the Frost boss & the Scion boss.
I'm solo btw...yes I know, I so need to find friends.

Anyways the 3 mages appear to be summoning too many adds for me to withstand. I've attempted just going after 1 mage at a time, but, all three summon adds I think & I can't seem to mechanic it to get even the first mage killed.
I'm 2H, medium, & granted ran out of crown store potions just before them, but at the rate I was exterminated each time swallowing Health potions, it wouldn't have mattered. Seriously well under 60 seconds.
Anyone solo'd this that can offer mechanics advice?
(I've been utlising
