You'll need to provide a screenshot of your roster. Good news tho, with the new UI you can fit way more champs in a single photo

Basicly you wanna nuke the starting line up, then keep buff stripping Odin's block damage.

I'm 100% on stage 30 with Gnut, Seer, Arbi, Lydia and Jack

Monkey is also a really good option for the team: nuke, strip, block

One min 

I'd go arbi, monkey, seer, freyja and ninja

I'll give them a go and see what happens 

You've got a pretty stacked roster and can easily do a budget team that works on stages 20+ 

Accuracy more than anything is gonna be needed for stages 25+ especially 30, which I can't do because I can't move the needed gear to the champs I'm using.

Uugo + Artak + Teodor can do the HP Burn team that functions similar to Spider. Since you have Seer tho, I suggest watching this video to understand the dungeon also, it's more than just slapping a team together

I use Siphi, Mithrala, Mikage, WuKong & Artak

It ia a burn & control team.  With Valk on the other team (L30), Mithrala keeps everyone petrified nicely due to the counterattacks w/Hex.  I am using Mikage in her alt form for strip & stun.  Armanz can fill in for Mikage nicely if you have him.  Of courdr, Seer is alos a strip option and she does nice damage.

My runs take about 2 mins on L30.          

I have played for awhile now and gotten lucky a time or two thanks tho I'll give it a watch and see what I can do my two teodors make short work of spider most of the time
