New group, strange rule.

[Devilkiller]

Hooray for Monks and Ninjas! Regarding the original question, getting an extra die of damage for beating the opponent's AC by 10 doesn't sound bad for attacks on regular AC. You might want to discuss not using this rule for touch attacks though. You could also consider using regular AC to calculate the extra damage even if the attack was a touch attack. That way armor would still protect you from Scorching Ray a little bit.

Two interesting side effects of this rule would be to make True Strike better (especially for a Magus) and to enhance the value of high AC. I guess it would also (very slightly) devalue Power Attack and boost Smite Evil a little.

Monsters brutes are going to destroy your party double the damage from Ogre Magi and various kind of giants is not fun at all with their high attack bonuses, prepare for pain.

I also agree that such a house rule brings
a) too much complications
b) rules questions
c) balance issues

Image an enervation that gets 10 or 20 points over the touch AC, now it's equal or better than the 9th level energy drain.

If it adds base weapon damage again, I don't foresee this being an issue.Especially if you treat it as a separate bonus (which it should be).

That said, it will by far favor monsters rather than PCs, and basically punishes low AC people, who really can't take the additional punishment, not the standard melee faire in the group, who should already have reasonable ACs.

I swear, you practically demand everyone play a Rogue/Ninja or Monk.

I was "practically demanding" that, huh?

I swear: your obstinate refusal to comprehend anything I write, and baiting across threads, is becoming tedious.
