Teacher

Prerequisite: You must have at least one level in a full spell caster class.

You have learned each spell at least once so why not share that gift with others? Over the course of 5 long rests per level of the spell (maximum spell level of 5) you teach you can teach an ally who is with you a maximum of 1 spell that they do not know and you do. They must also have a spell slot they can use to cast the spell with. This process costs 30 gold for each spell they learn in targets and materials to cast the spell. This cost is divided over each long rest that us used for this feat.
