I've been on-and-off working on a guide for magic items that work with class abilities, and have come up to a headscratcher.
The barbarian gets a +2 morale bonus to Will saves. A courageous weapon applies its enhancement bonus as a morale bonus against fear saves, and increases morale bonuses from other sources by half the weapon's enhancement bonus.
So assuming that a barbarian is wielding a +2 courageous greatsword, what does his Will save vs fear end up as?
Is it 3 (+2 class bonus plus half enhancement)? Or does the fact that the courageous morale bonus applies only to saves vs fear mean that it stacks with the Will save bonus, ending up with +5 vs fear?
The developers have admitted fault with the description of the courageous enchantment. I don't have the link, but I'm sure you can google it. There is some official clarification of the ability.
Thanks.
