General Feat (Prerequisite: Level 4+, Familiar Friend Feat)
You gain the following benefits.
Ability Score Increase. Increase one ability score of your choice by 1, to a maximum of 20.
Battle Familiar. You always have the Battle Familiar spell prepared. You can cast it once without a spell slot, and you regain the ability to cast it in this way when you finish a Long Rest. You can also cast the spell using any spell slots you have of the appropriate level. Your spellcasting ability for this spell is the one chosen for the Faithful Companion benefit of your Familiar Friend feat.
Intercept Attack. When a creature within 5 feet of your familiar is hit by an attack roll, your familiar can take a Reaction to add a bonus to the creature’s Armor Class against that attack, potentially causing the attack to miss. The bonus is equal to your Proficiency Bonus.
