where specifically are you getting stuck? i don't think you've reached the point where you can use a single team for all of doom tower so you're better off searching for comps for the floors giving you trouble .

+1 to Carpe's question.

What's your core team you're using at the moment?

I need help with all the bosses.  The only solid team that I have is Nether Spider.  So far, I have not been stuck on any level.  I have only been as high as 79.  

This is a really open-ended question. I don't think anyone is going to be able to answer you without writing a thesis-length response :/

And sadly, you're missing the true MVP of Doom Tower - Vogoth. No joke, most boss fights can be solved by just throwing more Vogoths at it.

I complete most battles in 2:00 or less.  A few times it has gone as long as 6:00

We can forget about the DT levels until I get stuck.  What about the bosses on the current rotation?

Coldheart and whoever that person in the #1 slot is, are totally useless for DT. Drop them ASAP.

Your core wave team should be:

1. Psylar
2. Scyl (booked)
3. Duchess
4. AOE HP Burn
5. AOE Provoke

@kramaswamy.kr .... I use Duchess for her aura.  Scyl is fully booked.  Kallia is the best HP burn that I have.  Visix will be AoE provoke.  I will add Psylar.  Give it a try.  

Thx.
