I gave my final stats in a post above.
While I did have trouble with my hit rate a couple times, it wasn't a persistent problem, and could be easily rectified by better equipment or a change in stat point distribution the next time I leveled (if I didn't have any points in reserve), etc.
It wasn't until very near the end of the game that I had the BF merchants offer me some holy water, and I was able to make some permanent potions. The 48 extra points (8 stat points per potion on action or tactical difficulty, one holy water from a quest and 5 from the BF merchants) certainly helped with the final fight, but I wasn't struggling before then.
I switched my hero to a bow for the last 3 or 4 fights of the game, and used the holy water to make permanent agility potions.
When I bought the holy water (before using it) I was still using a crossbow, and my stats were as follows, equipped and (unequipped).
