Beastmaster

Animal Companions

Gaining the trust of an animal is an arduous task, and for most beast masters is their pride and joy in life. This rite of passage is something no beast master takes lightly, and does so alone.
The first task of a beast master when gaining a companion is to determine which beast they wish to tame. Rangers are always mindful of the creatures around them, and at 3rd level have the right to tame one for themselves. Once a beast master has figured what type of beast they would like to tame, they need to track down the creature.
To successfully track a creature the beast master must make a survival check against the creatures stealth DC.
Animals in the wild live on a hierarchy of power and domination. Each creature bows down, or avoids those that can kill it or exploit it. As such a beast will not go easily along with someone it believes does not deserve it's respect. Using a weapon, or tool will not garner respect but fear - and rightfully so, a master may only use his wit, and brawn to tame a beast effectively. Once the master has found the animal, they need to break in the creature to gain it's respect.
To successfully break a beast the master must make a athletics or acrobatics check against the beasts athletics or acrobatics DC
Finally, a beast master must gain the loyalty and friendship of the beast, as described in the table below. This is the final prerequisite for a master in pursuit of a companion. The master must show kindness above all else to this beast, and this can be done in a multitude of ways.
Carnivore: Hunt with the animal and eating with it.
Herbivore: Moving with it's herd, and escaping predators together.
This bond is tightly woven, and will end only by death. But beastmasters know to beware, an extreme clash of interest can also cause the companion to distrust it's master, and leave.

Loyalty Table

---

Beast Loyalty	Requirements	Description
Subordination	None	At this level a beast follows your commands out of submission - the beast must be lead, and secured at night. If you are incapacitated, fall unconscious, or not present for whatever reason, the beast will flee.
Loyalty	Loyalty Building	At this level the beast will protect you. If you are incapacitated or fall unconscious, they will attempt to protect you from any hostile creatures, up to the point it would lose it's own life
Devotion	Prove your willingness to die for the creature	If you are incapacitated or unconscious, the animal will do everything it can to save you - up to risking its own life. Also, when either you or your companion are knocked unconscious, you have the ability to stabilize one another, as if they had rolled a nat 20 on a death saving throw.

At 3rd level a beastmaster gains maneuver points equal to a third of their ranger level. At loyalty level: loyal a companion can begin to learn maneuvers from their master equal to the max number of maneuver points available. It requires at least two long rests to teach the companion the new maneuver. A loyal companion can learn only basic maneuvers. A devoted companion can learn basic or conditional maneuvers.
Any DC is equal to the ability modifier called for plus proficiency.
