Side note: In the party I'm DM'ing, there's a 7th level fighter/ranger/barbarian combo with a 22 strength and a +1 Greatsword. Sent him up against a demon with damage reduction 20/+2. What's scary is that between Bull's Strength, Rage, and Power Attack, he was whupping the guy, even after the first 20 points were taken off. Assuming he power attacks for only 5, it's 2d6+1+15+5 = 28pts per hit. Ah, with Bard's song, 29pts per hit. Even at only 9pts per hit after damage reduction, it was enough to gradually mow demon-boy down. Ouch!
