I haven't gotten to try one over 145 yet. I did a run against king with sharks, and squirrels in the 140 range earlier tonight. Server 7
I used plant, monk, cyclops bard/dracul (I forget which, I switch my DPS up as needed), and healer.
The nice thing about using plant and monk together to tank the temples is that plant will keep monk alive while he charges, and as soon as her white skill is ready, she hops out of the way, lets monk tank and buff, and the defense cycle starts. Between Healer, Monk, and Plant, I can take out a lot of titans that are giving other people trouble.
There might be more minor strategies, but you have two choices... out-damage them, or outlast them. I play to outlast them in the temple. It might be a little slower to get my team rolling, but if it survives the first couple volleys, then as long as my DPS do enough damage, I win.
I modify my two DPS guys to fit the titans/minions.
My goto DPS atm are:
Bard+Cyclops (Sharks, squirrels, General balanced team)
Bard+Genie (Red Imps, Mushrooms, or following understudy)
Cyclops+Genie (mushrooms, or following understudy)
Cyclops+Dracul (Squirrels, Stone Imps, General magic damage team)
I've got a few different combos I use once in a while for other minions like , but I can't think of them all right now without looking at it in the game. Don't trap yourself into trying to find one team to do everything. You have three tries, so if you know for sure you can beat the team with your usual team, you can use one or two of your other attacks to mix it up and try new teams.
