A couple of questions regarding weapon enhancements:
1. If I have a +1 weapon, however it has the equivalent to +4 bonus due to special abilities, does this weapon overcome DR as a +1 weapon or a +4 weapon?
2. Again, If I have a +4 equivalent weapon, with one of the special abilities being courageous, but still only +1 enhancement bonus, will this weapon provide a +1 or +2 morale bonus? I'm thinking Courageous might be good for a barbarian to have, along with Furious.
Thank you.
AFAIK, no effects that refer to the enhancement bonus pay any attention to plus-equivalent special abilities. They're only plus-equivalent for pricing purposes.
