What have you been trying to run?  Psylar in a stun set, 2x CH, Visix and Madame should give you enough control and damage to push thru it.

Where is mithrala?

Where us Rian the DT epic?

Indeed , where is mithrala ? 

I did mine with mithrala , visix , serris , coldheart and Temila , went way too good , i suspect , because of mithrala ..

Rian is so good in Dark Elf crypt, sure. But Kaiden is excellent in DE crypt as well. I finished DE before I had Rian, and used Kaiden as my reviver.

Psylar, Coldheart, Visix, Madame and Kaiden should get this done. If you're low on damage, can always remove Psylar for a second Coldheart since you have two built.

sadly, i do not have Mithrala... hate going against her in arena... but when i get her i will be excited!

will give this a shot!  TY!

Imho a fast Psylar (in stun set) is the main cog here, because she gets everything and everyone else going.

From there on there are 2 valid path

Full control with 2 coldhearts, Visix and Madame Serris or full damage with Visix, Madame Serris, Maranix and Ruel. I really do like the Maranix/Ruel combo due to their synergy, but it seems that yours are not fully build up yet.

Never pla Kaiden, so can't say anything about his impact

Hopefully you can grab Mithrala soon. Hex with her passive is just going to nullify the waves, and then her cleanse on the boss is huge.
