You can unlock more Boon options from each Animal Spirit by spending Druidic Spirit Offerings that drop from slain monsters, and can switch between these Boons at any time (the Snake doesn't trust humans, so you'll need to unlock all four of its Boons at once with 100 offerings). After finishing it, you'll be able to activate one Boon from each of the four different Animal Spirits - Deer, Eagle, Snake, and Wolf - with each Boon giving you a special bonus. At Level 15, you'll get a Priority Quest called Spirits of the Lost Grove that directs you to visit the Druid Ardreth in Túr Dúlra, Scolsgen. Spirit Boons: The Druid's unique class mechanic in Diablo 4 is the Spirit Boon system. This lack of mobility can make it very difficult to escape a sticky situation. As tanky as Druids can be with the right setup, they're also the second slowest class after the Necromancer. With that said, you shouldn't be overly aggressive, as you don't have resource degradation to worry about like Barbarians do. Since Spirit generation requires active use of your Basic skills, you'll need to be fairly aggressive while playing as a Druid. Once you have some Spirit, it will remain until you use it. However, unlike Fury, Spirit is not lost between fights. The Druid's resource is Spirit, and like the Barbarian's Fury, it doesn't regenerate passively and must be built up and replenished by using Basic skills.

Understanding Spirit: Each class has a resource they need to generate and then use as a 'battery' for their main combat skills.
