Druid Circle: Circle of the Sun
Druids of the Circle of the Sun are nurturers of the wilderness. They make pacts and bonds with the beasts of nature. Their companionship with animals are built on a primal level within their very souls. A promise to take care of one another.
Druid's Companion
At 2nd level, you gain a beast companion that accompanies you on your adventures and is trained to fight alongside you. Choose a beast that is no larger than Medium and that has a challenge rating of 1/4 or lower (Appendix D presents statistics for the hawk, mastiff, and panther as examples). Add your proficiency bonus to the beast's AC, attack rolls, and damage rolls, as well as to saving throws and skills it is proficient in. Its hit point maximum equals its normal maximum or four times your druid level, whichever is higher.
The beast obeys your commands as best as it can. It takes its turn on your initiative, though it doesn't take an action unless you command it to. On your turn, you can verbally command it to. On your turn, you can verbally command the beast where to move (no action required by you). You can use your action to verbally command it to take the Attack, Dash, Disengage, Dodge, or Help action. Once you have the Extra Attack feature, you can make one weapon attack yourself when you command the beast to take the Attack action.
The beast understands Druidic, but does not gain the ability to speak it if they are unable to speak a language as is.
If the beast dies, you can obtain another one by spending 8 hours magically bonding with another beast that isn't hostile to you, either the same type of beast as before or a different one.
Exceptional Training
Beginning at 6th level, on any of your turns when your beast companion doesn’t attack, you can use a bonus action to command the beast to take the Dash, Disengage, Dodge, or Help action on its turn.
Share Spells
Beginning at 10th level, when you cast a spell targeting yourself, you can also affect your beast companion with the spell if the beast is within 30 feet of you.
Bestial Fury
Starting at 14th level, your beast companion can make two attacks when you command it to use the Attack action.
