Game Mechanics: Ridiculous Critical Resist Rate for Necromancer Lulls

[Splorf22]

I have been trying out a necro and aside from the fact that I have yet to get a single group invite over 3 levels I've been doing ok. However, I have noticed that Rest the Dead has an insanely high critical resist rate compared to what I am used to on an Enchanter. Unfortunately this is not easy to parse from logs but I would guess about 75% of resists are critical. Basically I've gotten to the point where any time I get a critical resist I automatically FD. If I had to guess, I would bet that necromancer lull is charisma dependent and probably should not be.
