I did my first try at solo cruci yesterday. My leader was a necro with maxed clay golem plus synergies. I didn't bother investing points in any damage skills as I know that my gear is not strong enough to support both tanky golems and a nice damage output. I managed to get to lvl 14 before I ran over the time limit. The necro seemed quite safe up to that point and as long as you have a nice damage dealer (and are able to clear stuff faster than I can), you shouldn't have too much trouble to get to lvl 15/16. I wonder how strong enemies will become beyond lvl 15. My strategy will go down the drain as soon as they start to hit hard enough to kill the golems.

Does anyone have any experience with golem survivability beyond level 15?
