As you know, ARC has only one RPG system bonus gift: ARC-BA (Battlemaster), which is an a-1 (i.e., +3). ARC-RT (Ritual) can make a token-3 story-token, but that isn't usable for a bonus.
If one goes the WAR gift route, WAR-AM (Artillery) and WAR-BM (Battlefield) can make token-3 and token-6 bonus-token story-tokens, respectively. However, I normally consider such to be "large area effects", so while I might use those in a particular situation for a bonus, the color that goes along with it is that it affects more than just a single target.
Of course, it is possible to get other bonus gifts, but those are not magic-related, but rather situational. So, I've been thinking about trying to design a (or some) new gift(s) that could be an a-2 class bonus (+6) and/or focus-based bonus. One might consider this to be a magical FGT-like gift, perhaps.
I was wondering if anyone had started along this path, so we don't duplicate efforts. Also, if anyone has any ideas about the color involved with these gifts, or the mechanics, I'd be interested in hearing them.
