Boon of Multiple Talents

You gain the following benefits.

Ability Score Increase. Increase one ability score of your choice by 1, to a maximum of 30.

Multi-Talent. Choose a subclass from any class you have at least 3 levels in, which you have not selected via this feat. You gain all subclass features of one chosen level that is lower or equal to the levels you have in its corresponding class if the feature does not require another subclass feature as prerequisite, which you do not already have.
