The Forest Fiend

The heart of the forest does not think, It can only feel. All actions must be done through the natural cycle of the world. The heart cannot help but desire aid, protection, and punishment for those who mistreat it. From this desire was born a spirit of protection who took a humanoid form. However it could not hope to stand against the force of sapience in large civilizations. The Forest Fiend, as they called it, would follow and attack any creature that entered the forest line. It would take the shape of any predator animal and allow itself to be hurt or captured before healing itself and killing everyone at the creatures base camp. Eventually it concluded that this was not enough. Encroachment on its territory and the loss of life was becoming more than a single being could handle. Sadness turned to despair and hatred. The protective spirit in the being had changed and turned villainous. The being would stop at nothing but the annihilation of all mortal civilization. To that end, it devoured the heart of the forest that birthed it and with its immense power launched an attack against the neighboring kingdom. The neighboring kingdom could not hope but to crumble underneath the might of the Forest Fiend, and its legion of beasts. However, the fight was not without casualties and the Forest Fiend fell in battle. While it may have won the battle, it knows it failed to win the war. Now the Forest Fiend resides in the Deep Forest, serving under Silvanus as a Weapon being sharpened for an attack.

Expanded Spell list

The Forest Fiend Spells

 

Bonus Cantrips

At 1st level, you learn the Primal Savagery and Thorn Whip cantrips. They count as warlock cantrips for you, but they don’t count against your number of cantrips known.

Fiendish Beast Shape

Starting at 1st level, you can use your action to magically assume the shape of a beast that you have seen before. This beast always has a fiendish twist to it. Such as Black eyes, unnatural horns, pale skin or fur or feathers, a combination of these, or any other fiendish characteristic you may think of. You can use this feature up to your Charisma modifier. You regain expended uses when you finish a short or long rest

Your Warlock level determines the beasts you can transform into, as shown in the Beast Shapes table.

Beast Shapes

You can stay in a beast shape for a number of Minutes equal to half your Warlock level (rounded down) with a minimum of 1 minute. When you run out of Beast Shape charges and revert to your normal form you can expend a Spell slot to change form again. You can revert to your normal form at any time on your turn. You automatically revert if you fall unconscious, drop to 0 hit points, or die.

While you are transformed, the following rules apply:

• Any creature properties that are not shown in the properties block are copied from your character. Such as Languages and Proficiency Bonus.
• When you transform, you assume the beast’s hit points and Hit Dice. When you revert to your normal form, you return to the number of hit points you had before you transformed. However, if you revert as a result of dropping to 0 hit points, any excess damage carries over to your normal form. For example, if you take 10 damage in animal form and have only 1 hit point left, you revert and take 9 damage. As long as the excess damage doesn’t reduce your normal form to 0 hit points, you aren’t knocked unconscious.
• You can’t cast spells, and your ability to speak or take any action that requires hands is limited to the capabilities of your beast form. Transforming doesn’t break your concentration on a spell you’ve already cast, however, or prevent you from taking actions that are part of a spell, such as call lightning, that you’ve already cast.
• You retain the benefit of any features from your class, race, or other source and can use them if the new form is physically capable of doing so. However, you can’t use any of your special senses, such as darkvision, unless your new form also has that sense.
• You choose whether your equipment falls to the ground in your space, merges into your new form, or is worn by it. Worn equipment functions as normal, but the DM decides whether it is practical for the new form to wear a piece of equipment, based on the creature’s shape and size. Your equipment doesn’t change size or shape to match the new form, and any equipment that the new form can’t wear must either fall to the ground or merge with it. Equipment that merges with the form has no effect until you leave the form.

Beast Cast

At 6th level, Through many battles you have proved to The Forest Fiend that you are worth further investment. You gain the knowledge to cast Cantrips while in your Fiend Beast form. Furthermore, at 12th level you can cast any known spell while transformed.
