Prerequisite: be trained in Animal Handling
You may now attempt to tame any wild (non-humanoid) creature to become your partner and companion. Make an Animal Handling check with a DC = 10 + the CR of the creature, made with disadvantage if you are in combat. On a success the creature becomes a temporary ally that you can command with a bonus action. They have their own initiative and will take the Dodge action if they are not given any orders. If the biology of the creature is able to you may also ride the creature as a mount (though a specially made saddle will need to be made to stay on the creature without disadvantage).
Each day after taming the creature you must remake the skill check to keep the creature tamed. On a fail the creature becomes disobedient and makes any orders you give it with disadvantage. Fail again and the creature flees. If you succeed on these checks three times the creature becomes a companion and won't become disobedient unless you purposefully harm it or put it in harms way against its will. You can have a number of tamed creatures equal to your proficiency modifier.
