Throughout. Replace "Intelligence check" with "Intelligence roll," "Perception check" with "Perception roll," and so forth. In Nomine makes rolls, not checks.
P. 2. Angels prefer selflessness, thinking of the group above the individual. (Not the whole. Oops.)
Kris' Ranged Weapon skill on page 4 is 4, not 2.
P. 4. Merari's Song of Thunder target number is not given in the text. It should have the target number of 9.
P. 5. Local History box. Replace "check" with "roll." In Nomine has one make rolls, not checks.
P. 6. Replace "unsummoning ritual" with "banishing ritual" everywhere it occurs on this page.
P. 8. In Ummah's description of her powers, "you are unaffected by this song." should be "you are unaffected." (It's her resonance, not a Song.)
