if you could teach a flock of crows any spell from D&D, which one would you pick
The crows are not your minions, they will choose to learn or not learn the spell based on their own interests and will only use it for their own purposes so choose wisely
i think crows would be very interested in vicious mockery and mage hand, personally

@Lady probably, but i dont think that would necessarily count as a spell
