Familiar Trainer

When you take this feat, you may train familiars and add your proficiency modifier to their AC, skill checks, saves, DC and to hit rolls for weapon attacks and spell attacks. Additionally, you can come in your familiar as a bonus action instead of an action.

Taking this feat allows you to train your familiar in new ways by allowing them to gain levels and you may train them in maneuvers and feats they typically would not be able to learn. (Chart provided on leveling familiar)
