I play in two 3.5-campaigns with two different DMs. In one of them, an (non-magical) arrow shot from a +1 magical longbow makes 1d8+1 damage. In the other, it makes 1d8 damage, but it counts as magical damage. Which is "right"?
The DMG (p221) says:
It doesn't really specify whether the bonus counts for the damage or not. So, what to you experts say?
The DMG (p221) says:
Ranged Weapons and Ammunition: The enhancement bonus from a ranged weapon does not stack with the enhancement bonus from ammunition. Only the higher of the two enhancement bonuses applies.
Ammunition fired from a projectile weapon with an enhancement bonus of +1 or higher is treated as a magic weapon for the purpose of overcoming damage reduction. For example, a sling stone hurled from a +1 sling is treated as a magic weapon. Similarly, ammunition fired from a projectile weapon with an alignment (such as a +1 holy longbow or a masterwork crossbow under the effect of the align weapon spell) gains the alignment of that projectile weapon (in addition to any alignment it may already have). For example, a +1 unholy arrow fired from a +2 anarchic shortbow would be both evil-aligned and chaos-aligned (the former from its own unholy special ability, the latter from the shortbow).
