One of the missions wanted a pet, but Daisy doesn't count because of her beastkin variant, the Natural Pet.  It might be good for some quests to specify whether certain things are disallowed - hermaphrodites, beasts, ect.

My thought on the servant-based quests:  maybe there should be some wiggle room for the requirements, provided that the assigned servant has enough skills to compensate for not being wholly correct for the task.  Of course, some missions should have hardline positions on parameters, with better rewards but lower margins of error.

I know what you mean, the pet trait is only available for humans and maybe one or two other species and all others have the natural pet trait, which is basicly the same but makes a difference at tasks
