Druid: Circle of Oaks

There is power in the ancient trees of the world—a quiet, abiding power. Those who live among trees, like the elves, are aware of this power, and they treat it with respect, even reverence. Some druids learn to tap into this power. These are the members of the Circle of Oaks. By suffusing themselves with the vitality and strength of the ancient green, they can perform mighty feats. Although they commonly hail from the ancient forests of the world, Circle of Oaks druids can be found anywhere there are trees of sufficient age from which to draw power.

Circle Forms

The rites of your circle grant you the ability to transform into more dangerous animal and plant forms. Starting at 2nd level, you can use your Wild Shape to transform into a beast or plant with a challenge rating as high as 1. You ignore the Max. CR column of the Beast Shapes table, but must abide by the other limitations there.
Starting at 6th level, you can transform into a beast or plant with a challenge rating as high as your druid level divided by 3, rounded down.

Tree Step

Starting at 6th level, you can spend half your movement to magically step into a tree and transport yourself through it and out of another tree of the same kind within 60 feet, reappearing in a space of your choice within 5 feet of the destination tree. You can use this feature twice when you reach 10th level, and three times at 14th level, when the range becomes 120 feet. You regain all expended uses when you finish a long rest.

Might of the Oak

At 10th level, you can expend two uses of Wild Shape at the same time to transform into a treant without the Animate Trees feature.

Rouse the Grove

At 14th level, you can use an action on your turn to stir the trees around you, bringing them to your aid. All trees within 60 feet of you become animated, their roots churning the earth and their branches whipping and slashing. All spaces within 15 feet of a tree are considered difficult terrain for your enemies, but not for you or your allies. A creature concentrating on a spell that starts its turn in one of the affected spaces must succeed on a Constitution saving throw against your spell save DC or lose concentration on the spell.
Also, you can use a bonus action on your turn to cause one affected tree to strike a creature within 15 feet of it with a branch. Make an attack roll, using your spellcasting ability modifier as a bonus to the roll. On a hit, the creature takes 4d6 bludgeoning damage. You can use this feature for a number of rounds equal to your druid level; these rounds need not be consecutive. You regain the full use of this feature when you finish a long rest.
If this feature is used underground, beneath an area where trees grow, the effect is the same, except it is the trees’ roots that burst through walls into rooms or tunnels, producing the same effects. If the GM decides the area is too far underground or is otherwise unsuitable for this feature to be used, it has no effect.
