duchess scyl ult galek drexthar coldheart should work even if not pretty

fayne instead of drexthar would be faster, just not sure about the speed/gear of your team

Seems to me Drexthar is the key - both for the HP burn and as off-affinity tank. Make sure he has enough resistance. Though Duchess' veils might throw off spiderling targeting I guess... 

Visix could be decent as well, so CH isn't the only one controlling the turn meter. 

What did you use for spider 19?

i cant beat spider lvl 19 either. totally, totally unfair. im not going to spend 10g to get past it. That and brimstone 7 on nightmare. Game is way way to expensive to play. Time to go start buying games again its definitly cheaper.
