These druids make it their mission to protect life, whether that is plant, animal or people. They will often travel in groups to help others, sometimes as things other than druids.
Speech of the Woods
At 2nd level, you learn to speak, read, and write Sylvan. In addition, beasts can understand your speech, and you gain the ability to decipher their noises and motions. Most beasts lack the intelligence to convey or understand sophisticated concepts, but a friendly beast could relay what it has seen or heard in the recent past. This ability doesn't grant you any special friendship with beasts, though you can combine this ability with gifts to curry favor.
Spirit Totem
Starting at 2nd level, as a bonus action, you can magically summon an incorporeal spirit to a point you can see within 60 feet of you. The spirit creates an aura in a 30-foot radius around that point. It counts as neither a creature nor an object, though it has the spectral appearance of the creature it represents.
As a bonus action, you can move the spirit up to 60 feet to a point you can see.
The spirit persists for 1 minute or until you're incapacitated. Once you use this feature, you can't use it again until you finish a short or long rest.
The effect of the spirit's aura depends on the type of spirit you summon from the options below.
Bear Spirit: Each creature of your choice in the aura when the spirit appears each gain temporary hit points equal to 5 + your druid level. In addition, you and your allies gain advantage on Strength checks and Strength saving throws while in the aura.
Hawk Spirit: When a creature makes an attack roll against a target in the spirit's aura, you can use your reaction to grant advantage to that attack roll. In addition, you and your allies have advantage on Wisdom (Perception) checks while in the aura.
Unicorn Spirit: You and your allies gain advantage on all ability checks made to detect creatures in the spirit's aura. In addition, if you cast a spell with a spell slot that restores hit points to anyone inside or outside the aura, each creature of your choice in the aura also regains hit points equal to your druid level.
Mighty Summoner
At 6th level, any beast or fey summoned or created by your spells gains the following benefits:
Its hit point maximum increases by 2 per Hit Die.
The damage from its natural weapons is considered magical for the purpose of overcoming immunity and resistance to nonmagical attacks and damage.
Guardian Spirit
Beginning at 10th level, when a beast or fey that you summoned or created with a spell ends its turn in your Spirit Totem aura, that creature regains a number of hit points equal to half your druid level.
Faithful Summons
Starting at 14th level, if you are reduced to 0 hit points or are incapacitated against your will, you can immediately gain the benefits of Conjure Animals as if it were cast with a 9th-level spell slot. It summons four beasts of your choice that are challenge rating 2 or lower. The conjured beasts appear within 20 feet of you. If they receive no commands from you, they protect you from harm and attack your foes. The spell lasts for 1 hour, requiring no concentration, or until you dismiss it (no action required).
Once you use this feature, you can't use it again until you finish a long rest.
