Inugami Companion

Your Inugami counts as an Animal Companion when you summon her.

Companion's Bond

Your animal companion has abilities and game statistics determined in part by your level. Your companion uses your proficiency bonus rather than its own. In addition to the areas where it normally uses its proficiency bonus, an animal companion also adds its proficiency bonus to its AC and to its damage rolls.
Your animal companion gains proficiency in two skills of your choice. It also becomes proficient with all saving throws.
For each level you gain after 3rd, your animal companion gains an additional hit die and increases its hit points accordingly.
Whenever you gain the Ability Score Improvement class feature, your companion’s abilities also improve. Your companion can increase one ability score of your choice by 2, or it can increase two ability scores of your choice by 1. As normal, your companion can’t increase an ability score above 20 using this feature unless its description specifies otherwise.

Coordinated Attack

Beginning at 5th level, you and your animal companion form a more potent fighting team. When you use your action on your turn to cast a spell or cantrip, if your companion can see you, it can use its reaction to make a melee attack.

Beast's Defense

At 7th level, while your companion can see you, it has advantage on all saving throws.

Storm of Claw and Fangs

At 11th level, your companion can use its action to make a melee attack against each creature of its choice within 5 feet of it, with a separate attack roll for each target.

Superior Beast's Defense

At 15th level, whenever an attacker that your companion can see hits it with an attack, it can use its reaction to halve the attack’s damage against it.
