I rolled a 16 for attack, what do i add to determine how successful it was? And is it versus anything?

It's Vs his tiny agi score, and you don't necessarily add any damage, given that a crit would happen at 20 for you, however, you should be able to do about 4 damage (with each fist), 'cause fists ignore added armor (but aren't always too powerful)
