If the goal is for Team Sun to engage in skirmishing and do a lot of collateral damage, it would make sense for the group to operate in essentially two teams:

Bear-handlers, who primarily goad/engage the bear and aggress on the Seelie when they can outside of that, traveling alongside the second group--

Warriors, who attack in a radius around the bear, thinning down threats that might, combined, take the bear down easily, and who are also free to do as much additional damage as possible.

Since they're coming into this expecting battle and wanting to do collateral damage, would Grell be opposed to using incendiaries?
