For those who are unfamiliar with it, the spell Blood Crow Strike allows you to make unarmed attacks or a flurry of blows at medium range against the target of the spell, rather than just within your reach. It also makes the damage apply as half fire and half negative energy, but that isn't the focus of my question.
It specifically calls out Flurry of Blows in the text of the spell, which indicates that it is meant to be used by monks, but it is a 4th level cleric/oracle spell, which means that you have to either be heavily multi-classed (not a good option for flurry of blows), or you have to get this as a scroll or wand. Given that monks typically have bad charisma, and therefore a bad Use Magic Device score, that makes it even more difficult to use. But it seems strange to me to have a spell that is only useful as a scroll or wand, and not for the original class.
Normally I would expect a spell like this to have the target be an ally, with some kind of duration that would allow that ally to then use their unarmed strikes at range. For example, Magic Weapon targets a weapon which can then be used against enemies, and Enlarge Person targets a humanoid, which would then be able to use the benefits of the spell during their combat. That wouldn't necessarily be a great use of a spell, but it would fill a useful niche.
Am I misunderstanding or misreading this spell? If not, is there a way that this would ever be useful for a cleric or oracle to cast?
