Every playable class in Diablo 4 has a unique mechanic that is specific to them. The Rogues have Specializations, the Sorcerers have Enchantments, and so on. In regard to the Druid, players will have access to the Animal Spirits mechanic. While this mechanic is not playable in the Diablo 4 beta, we have enough of an understanding of Animal Spirits to describe it in-depth and predict how it will play out in the full game.

Diablo 4 Druid Animal Spirits mechanic

To start, the Animal Spirits system builds off of the Druid's ability to shapeshift into a wolf or bear and also have animals as companions. However, with Animal Spirits, players will be able to pick one of four different spirits at a time. The Animal Spirit they pick will offer them unique bonuses, which are called Boons in Diablo 4.

There's no word on what the Animal Spirits will be yet or what each of their Boons will be. Players could see an increase in their elemental damage, have their animal companions become stronger, or get some additional defensive buffs, but none of that has been confirmed by Blizzard as of yet.
