Beastmaster

The Beastmaster Druid can form a telepathic bond with various wild beasts. 

Druid Companion

During a Long Rest make a Spellcasting check, adding your modifier. If the result is 30 or higher your summoned beast has a CR of 1 or less. Examples include Brown Bear, Dire Wolf, Giant Eagle, Giant Spider, Lion, or Tiger. If you roll 25-29 your beast has a CR of 1/2 or less. Examples include Ape, Black Bear, Giant Goat, Swarm of Insects, or Wild Horse (warhorse). If you roll 20-24 your beast has a CR of 1/4 or less. Examples include Boar, Constrictor Snake, Elk, Giant Badger, Giant Owl, Giant Wolf Spider, Panther, or Wolf. If you roll 10-19 your beast has a CR of 1/8 or less. Examples include Blood Hawk, Flying Snake, Giant Rat, Giant Weasel, Mastiff, or Poisonous Snake. If the roll is less than 10 your beast has a CR of 0. Examples include Baboon, Badger, Bobcat (cat), Deer, Hawk, Owl, Spider, Weasel, or Wild Dog (jackal). The summoned beast should be appropriate for the environment you are in when you summon it.

Your animal companion has the maximum hit points for its species. It takes its turn on your initiative and obeys your mental and verbal commands as best as it can. On your turn you can command the beast to move as your bonus action and you can use your action to command it to take the Attack, Dash, Disengage, or Help action. If you don’t issue any commands the beast follows you and takes the Dodge action, if possible. If you are incapacitated or absent, the beast acts on its own, focusing on protecting you and itself. The beast never requires your command to use its reaction, such as when making an opportunity attack. You lose your connection with the beast if you are more than a mile away from it. You can only have one animal companion at a time, but you can dismiss your current companion as an action and summon another during your next long rest.

 

Improved Bond

Starting at level 3, add your proficiency bonus to your animal companion’s hit points, AC, attack rolls, and damage rolls, as well as to any saving throws and skill checks for skills it is proficient in.

Exceptional Bond

Beginning at 6th level you can use a bonus action to command your animal companion to take the Attack, Dash, Disengage, or Help action on its turn, in addition to its movement. 

Spell Sharing

Beginning at level 10, when you cast a spell targeting yourself, you can also affect your animal companion with the spell if the beast is within 30 feet of you. Also, the beast’s attacks now count as magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage.

Bestial Fury

Starting at 14th level you can command your animal companion to take its Attack action twice in one turn. It can do this once per short rest.
