Veteran's Scars gives 48 HP now, not 60. There were a noticeable handful of typos (5ish) and you didn't correctly use parentheses when doing math the first time, but then right afterward you had a large complex problem that was correctly parenthesized.
The mistake was regarding resistance. It was (100/100 + 100) instead of (100/(100 + 100)), which is a significant difference.
Everything else was too minor to care about, but typos nonetheless. Pardon me for being too lazy to go over them all.
This was in the .pdf, I'm not sure if the same mistakes are in your posts here.
