Vergis can solo him with Regen/immortal gear. Not sure if it works if he is only rank 5 but it is possible I would think I'm normal.

yes but as stated i dont have the regen gea r to do the solo builds 

I believe the core of your team should be Geo, Visier and Vrask. The other 2 put in somebody with lots of heals, like Apo and/or Scyl. You have a lot of good support champions at lv 50, I'd recommend bringing them to 6*. You're going to need them later on for general content, especially FW. 

Agreed on Geo/Vizier/Vrask. Would be super helpful to land the accuracy down from Geo, extend Vizier. Vrask for passive healing. Then I think I'd want Doompriest for more passive heals, making him fast to let him keep the team going. We lack some of damage mitigation I'd like to see, but maybe in the 5th slot we can try Stag Knight for speed down on A1, att/def down A2, or Ninja for raw DPS/bomb freeze. 

Stat thresholds might be a bit tight for you, but I think landing an acc down and keeping that going the whole time should make a big difference in keeping too many bombs from getting thrown on your champs. 

I would start bye upgrading Deacon to lvl 6 and then 60. (you gonna need him against Dark fay too)

Vergis should be next (or first)

I'm stuck at 90 but it's a gearing issue. Which sucks since I'm 1 fragment from having dark kael.  

Resistance seems awfully important for this one. 

Seems i was tight not a comp issue as normal but gear n lvled champs so off to grind more ty for ur advice funny he is the last doom tower normal boss I can't beat
