When I load the linked save game, the attacks I perform with a double handed axe on the battlemage seem to attack three times on a single attack as evidenced by three consecutive "miss" messages on the target. If I do hit, which is rare even with a 95% displayed to-hit chance, I only do 1 damage against level 5 skeletons even through my damage range is from ~50-~115.
