Primal Companion

The road is lonely often and not all companions need be humanoid, sometimes a loyal beast or wandering fey can be excellent company, as well as back up in a fight.
You may spend an hour long ritual summoning a beast companion to aid you in your adventures, this companion acts on your turn in combat, you may command it to take a specific action such as attack, disengage or hide using your bonus action, your companion may also move as a free action. 
Your chosen companion must meet these requirements:

• Be of a challenge rating equal or below 1/4 your character level (rounding up).
• Have an Intelligence score of 7 or lower.
• Able to understand at least one language (your companion understands you regardless of shared language).

Your companion also gains some additional benefits based on your character level and class:

• When you gain a level and increase your Hit Point Maximum your animal companion’s Hit Point Maximum increases equal to your roll plus their constitution modifier.
• When your companion deals damage you may add your proficiency bonus to the damage roll.
• When you gain a Ability score improvement you may also increase two of your companion’s scores by one or one of their scores by two.
• You gain proficiency with Animal Handling, in addition you may double your proficiency bonus when making skill checks.
