I soloed mythic sanctum yesterday on my warlock, but trying to do on my warrior today, kel’thuzad doesn’t seem doable. I kill the adds at first phase shift and enter portal, enemy is invisible so i spam aoe’s and “kill” it i think, sends me back to surface, and then this just repeats FOREVER. I killed him 6 times before just giving up. The adds never stop spawning. I thought this was supposed to be soloable now? Any suggestions?
I should add while I’m in the portal, the only confirmation I get that the add is dead inside is “immune” messages before it sends me back to surface.
Anyone else struggling, I guess I just wasn’t doing enough damage to the add inside before he went immune. Save cd’s and pop them inside and do as much non-targeted aoe as possible. Got him after 2 rounds.
