So I was hit for 2 negative levels.
Now, from what I can gather about negative levels, is that they apply the following, per negative level: "-1 attack rolls, saving throws, skill checks, ability checks; loss of 5 hit points; and -1 to effective level"
Now, from what I can see. Negative levels apply -2 to saves per negative level. About that much to attack rolls and skill checks.
Additionally, I had 144 hitpoints maximum. I took 2 negative levels and was at 116 maximum. That's 28 hitpoints, or 14 hitpoints per negative level!
Am I missing something here? And I'm wondering if the NPCs take these penalties or not from our enervations and such.
