Aaaah. Okay, I just looked at how bows are set up in the data, and that makes things. . . complicated.

Bows are set up to use weaponst(), which makes total sense because you buy a bow with some assigned ST, and the damage is based upon that, not upon your own ST.

However, there's no way to have a modifier give a bonus to weaponst(), because it's an ad hoc tag, and GCA can only give bonuses to tags it knows in advance how to handle.

That means you have two options:

1) A really complicated bonus from the modifier, which somehow checks what the trait it's being applied to is, and replaces the damage() tag with an appropriate one that includes the extra +2 to weaponst.

2) Change the weaponst() tag for every bow, so that the value it contains can look for the existence of the Elvin modifier, and include a bonus to itself if it is found.

Option 2 is a lot easier.
