I tried that with my first run of CoE this week, but found that my scatter grenades were not enough to kill the Taken on the last round? I switched to sunsinger and use that Viking thing and the grenades just melt the enemies. I will say I did not try void with the nothign manacls, maybe that will help? I can't imagine it will fully kill the enemies, but maybe just the fact that I will have more grenades will help? Thanks!
