Circle of Fusion

Druids of the Circle of Fusion are perhaps the Druids that are the closest to nature. Unlike most Druids they choose one specific Animal they embody for the rest of their lives. Over time the Druids partially adopt the Animals' physique and abilities to be even closer to nature. They are often mistaken for lycanthropes which is very unpleasant for both sides as it provokes rivalry between them. 

 

Most of the mechanics in this Subclass need to be managed manually as it can't be implemented in DnD Beyond.

Bonus Cantrip

When you choose this circle at 2nd level, you learn one additional druid cantrip of your choice. This cantrip doesn’t count against the number of druid cantrips you know.

Animalistic Focus

Choose one Creature that is a beast and CR 1 or lower and you may only turn into that specific Animal.

Additionally, your Wildshape is no longer limited by time and you gain a +1 to all ability scores while in your wildshape.

Wild Aspect

You may take one of your chosen Animal features (For example Keen Hearing and Smell for a Wolf) which you will now have permanently. (You can not choose Pack tactics.)

Beast Sense

At 6th level, you start to gain the Sense of Nature.

You're now constantly under the effect of speak with animals and you can telepathically communicate with Animals of your chosen species.

Additionally, you gain a sense of your chosen species. (Darkvision, Blindsight etc.)

Pack Leader

Once per Long rest you can expend all of your Wildshape charges and summon one creature, of your selected species, per charge expended. They do not gain the benefits of your Wildshape and go on the same initiative as you. You may control all of them at once as a bonus action, if you do not control them they will stay in place and ready an action to attack if the enemy approaches.

True Form

You no longer need to use Wild shape charges to enter your wild shape, your wild shape bonus increases to +2 and you can now choose to wildshape a willing ally into your chosen species. If you and at least one ally are wildshaped you both gain pack tactics.
