Quote:
no. an AB bonus just provides AB and enchantment is both AB and damage. the higher AB bonus will show, and the enchantment damage will show.
for example:
+5 ab
+4 enchant
is +5 attack bonus and +4 damage
+3 ab
+4 enchant
is +4 to attack and damage. the +3 ab is overridden
This. And for the record, if you have a weapon thats +5 AB, it cuts through DR that is, say, 20/+5, just like enhancement would.
The only difference between enhancement and AB, is damage.
