The modifier next to a monster's ability scores is (actual modifer + 1/2 level). So the wyrmpriest (level 3) has: STR 9 (+0). That's its modifier for any sort of strength check, or strength-related skill check.breschau said:Thank you so much. That's a wonderful job. I did notice that the Kobold Wyrmpriest has STR 9 (+0) instead of 9 (-1). I'm not sure if that's a error that slipped in on your part or if it was from the original, but it is inconsistent with what we know of abilities and modifiers as well as other monsters who are listed with 9 (-1).
That said, I see a lot of typos in the ability modifiers of various kobolds (and possibly elsewhere) in the PDF.
Aside from the skeleton tomb guardian, the goblin picador's stats are also suspect. Its hit points are wrong, and it originally had an AC lower than its Ref defense. Which someone 'fixed' at some point, but between that and hp I don't trust the rest of the numbers.
