Casting cat's grace on yourself would raise your Dex to 16, giving you an additional +2.

Oops. Last night I mis-read and put it as a +4 to hit, rather than +4 to dex, which I realized while looking over the Level 7 upgrade. Which, given that when I needed it, it didn't help me, and when I didn't need it, it didn't make a difference, I don't think it affected The Outcome too much...

Ah well, a learning experience, always.
