Died for the first time, since I am done with the build. I was being stubborn, I did the whole RWZ arc on +1/x8, even the Gaussian part with the Vanguards and Longbows. Was doing fine but died then on the last mission. I am not very familiar with what they actually do, because my defenses did not drop, but I assume they got a lot of +tohit, because on a group with 3 bosses I went down pretty fast. Still unsure if it's actually +tohit, because I have no problems with Nemesis.
