In PnP, you get a +2 damage for all of your favored enemies, and a bonus +2 damage to ONE of your favored enemies every 5 levels.
Now, in DDO, there is no choice of which favored enemy to apply the bonus +2 damage to, so I am assuming that you get an additional +2 damage to all of your favored enemies every 5 levels.
Of course, none of this counts the bonuses for enhancements.
Has anyone tested this to see if this is how it works?
Thanks,
