Well, it started 18, +2 for race, +1 at lvl 4... I guess it was only 21. He's actually lvl 5 which helps. On second thought though, he's easily one of my best characters, and extremely cheap once you factor in feats, so I won't use him. You guys get the 20 AC fighter instead. I built him around the Weapon Finesse feat which means that he uses Dex instead of Str for attack rolls, so he does 1d20+11 to hit, high AC, and he's a boss with a bow. Essentially, I tried to build a character that was impossible to kill with high attack, so he has Diehard (he keeps fighting until he's at -10 health), and a bunch of weapon specialization feats. His damage isn't terrific, but it's amazing when he never gets hit and always hits other people.
So on that note, we're going to time skip back to town, since the desire to explore the mansion ended in a plot fall.
