Base Class: Warlock
Some say that the forests hold many spirits and beings that watch over what they were given to protect. Certain guardians are more merciful than others, but the Gnarlwood is vengeant to those who would betray the flora and fauna of the natural world, and guards all with a firm branch.
Expanded Spell List
When you choose The Gnarlwood as your patron at first level, you gain access to an expanded spell list, and can choose a Warlock spell to learn from this list.
1st Earth Tremor, Entangle
2nd Barkskin, Maximillian's Earthen Grasp
3rd Call Lightning, Erupting Earth
4th Grasping Vine, Stone Shape
5th Maelstrom, Wrath of Nature
Guarding Vines
The Gnarlwood will stop at nothing to protect those it must.
At 1st level, when you are hit by a melee attack, you can use your reaction to bind the target with vines. The target must succeed on a Strength saving throw against your spell save DC, or be restrained until it spends an action to break free. You may use this ability equal to your Charisma modifier per long rest.
Ever Watchful
The Gnarlwood is ever watchful of you and your adventures. When you reach 6th level in this class, so long as you are withing 30' of a large amount of nature (such as trees or wild creatures) and not unconscious, you cannot be surprised.
Also at 6th level, you can cast Clairvoyance on a tree you're familiar with, with no maximum range once per long rest. This does not consume a spell slot.
True Guardian
The Gnarlwood can summon many beings to their aid - and now, will allow you to summon a creature of great strength to your side.
When you reach 10th level, as an action and consuming a spell slot, you can animate a large tree within 60' of you into a treant to fight by your side for one minute. It follows a single command that you issue as a bonus action on this and any subsequent turn, and acts on your initiative. You may use this ability once per long rest.
Lost Forever
At 14th level, you choose a target to become lost in the maze of a long forgotten forest, no longer on the material plane. Once per long rest, you can cast the Maze spell on one creature, consuming a spell slot.
