Earthbound

Common in former druids, the devoted of certain gods, or those that were bound to elementals of the earth, the earthbound are slowly transforming into stone, metal, or wood.

This soulmark starts with rough patches of skin and a surprising density of bone. You were always tougher and slower than the other children. As your bond deepens, more and more of your flesh transforms into material that should be inanimate, and yet, for now, you can still walk.

Base Power: Durability

At first level, you gain Unarmored Defense. While you are not wearing any armor, your Armor Class equals 10 + your Dexterity modifier + your Constitution modifier. You can use a shield and still gain this benefit. If you have Unarmored Defense as a class feature, you may add +1 AC to whichever source provides the better AC.

Additionally, you have advantage on saving throws to resist becoming Poisoned or Stunned. However, you have disadvantage on saving throws to resist becoming Petrified.

Your weight is 10% higher than it would be if you were entirely flesh and blood.

Secondary Power: Rooting

Usually, the first part of your anatomy to become fully of the earth is your legs.

You can no longer wear most footwear, your legs gnarling into a stable platform, but you are immune to ground-based hazards that are intended to damage your feet (e.g.; caltrops, spike growth, etc.); you are still slowed by the difficult terrain of these hazards.

Your AC improves by +1, regardless of whether you are wearing armor.

When you are standing on stone, wood, or earth, you can use your move action to gain temporary hit points equal to your level. These hit points disappear if you leave your current space.

Your base walking speed is 25 feet, and your weight is now 40% higher than it would be if you were entirely flesh and blood.

Tertiary Power: Embrace

Often, the transformation only lightly covers the torso before covering the arms, providing just enough support to wield the now-restructured appendages.

Your arms are somewhat oversized and gnarled, and you may need to have gloves, bracers, and the like adjusted to fit. In particular, most gloves are immediately destroyed when you use your arms to attack. Your unarmed attacks now deal 1d6 bludgeoning damage and you are considered proficient. If your unarmed attack already did at least 1d6 damage (e.g., from feats or class abilities), increase their damage further by one die step.

Further, you may extend spikes or blades with concentration and a short or long rest, increasing the damage to 1d8 (slashing or piercing), or two steps if you are already proficient in unarmed attacks. You do not have a hand on the arm transformed in this way, so cannot engage in tasks that require fine manipulation. You can return your arm to normal with another short or long rest.

Similarly, you may transform an arm into a shield-like structure, granting you a shield bonus to AC. This takes the same amount of time to change or change back, and also counts as not having a hand on that arm while you have a shield.

You are immune to any poisons that enter through your hands (e.g., contact poisons, poison needle trap, etc.). You are similarly immune to most other hazards that would damage flesh but not inanimate objects if touched.

Your weight is now 70% higher than it would be if you were entirely flesh and blood.

Ultimate Power: Statuesque

As your transformation completes, you are functionally an animate statue or carving. Some small amounts of flesh and blood still hide beneath sessile skin, allowing you to age, procreate, eat, and breathe. But to onlookers, you no longer appear to be part of the animal kingdom.

You are resistant to bludgeoning, piercing, and slashing damage from nonmagical attacks, as well as to poison damage (from poison sources that can still manage to penetrate). If you gain resistance to such damage from a class ability (e.g., barbarian rage), instead treat your AC as an additional +2 against attacks to which you should be doubly resistant.

If you are made of stone, you are vulnerable to thunder. If you are made of wood, you are vulnerable to fire. If you are made of metal, you are vulnerable to lightning.

Any effect that is based on causing you to bleed or draining your blood automatically fails (you don’t have much blood in you).

You have advantage on Constitution saving throws.

Your base walking speed is 20 feet, and your weight is now 100% higher than it would be if you were entirely flesh and blood.

Beastheart

Often mistaken for lycanthropes or members of anthropomorphic animal races, beastheart soulmarked come by their gradual transformations due to an ancient allegiance to some form of bestial spirit. However, while they do not tend to pass on their animal characteristics to children, there is some speculation that they might still have been progenitors of bestial humanoid bloodlines on the rare occasions they’ve bred true. Typically, however, being of such a race indicates deep commitment to a spirit of the wild in a past life, and is particularly common for former rangers, totem barbarians, and circle of the moon druids.

This soulmark begins with a somewhat feral appearance, and gradually distorts the body into a hybrid of birth race and bonded animal. While any animal is possible, it is much more common to see a beastheart bound to an impressive predator totem than simply any form of animal. Inoffensive prey animals rarely make history.

Base Power: Feral

At first level, your form is not obviously animalistic, save for perhaps an additional hirsuteness and sharpness of features and teeth. However, the natural world is likely to treat you as a member in good standing. Animals react to you as if you were a member of your bonded animal type rather than as a humanoid: if you are a predator, prey animals are likely to flee and other predators to give you a wider berth than they might otherwise. You gain advantage on Wisdom (Animal Handling) checks. Additionally, you gain advantage on Charisma (Intimidate) checks made against beasts.

You gain one of the following abilities that is appropriate to your animal bond: darkvision (60 ft.), hold breath, keen smell, keen hearing, keen sight, or sure-footed. It works the same as the associated or similar animal as described in Appendix A of the Monster Manual.

Your base walking speed is 35 feet, and you may double your jumping distance (as if under a reduced effect of the jump spell).

Secondary Power: Vicious

Once your abilities begin to unlock, the first step is to gain the natural attack methods of your bonded animal. Depending on your animal type, your face may distort and teeth lengthen, your hands and feet may alter to support claws or talons, or you may even grow horns or antlers. Generally, while you can still pass as your parents’ race with some disguise effort or in dim lighting, your bestial nature is now readily apparent to onlookers with good light.

Your natural attack form counts as a finesse, light weapon in which you are proficient. It does 1d6 piercing or slashing damage (as appropriate), or 1d8 if you are proficient in martial weapons (the viciousness of the weapons is in some way contingent on your combat capabilities). It is also effectively versatile, increasing a die size if you make the attack as your primary weapon and do not use your off hand (for shield or secondary attack); this may look like attacking with both claws in a single strike or using your hands to grab the target to improve your ability to bite or gore.

Additionally, you gain one of the following abilities that is appropriate to your animal bond: amphibious, blindsight (60 ft.), charge*, climb speed (equal to walking speed), pack tactics, rampage, relentless**, or swim speed (equal to walking speed). It works the same as the associated or similar animal as described in Appendix A of the Monster Manual.

You count as a beast for magic that can affect them.

You can no longer hide your bestial features easily. They are obvious even in bad light, and onlookers have advantage on all rolls to see through attempts with illusion or physical disguise to hide your animal nature.

* This deals +1d6 damage and increases to +2d6 at 11th level. The target’s strength saving throw to avoid being knocked prone is at a difficulty equal to 8 + your Proficiency bonus + your Strength bonus.

** The threshold for damage that is reduced to leave you with 1 hit point is equal to three times your Proficiency bonus.

Tertiary Power: Mobile

At this stage, your musculature and skeleton has adapted for motion. Your legs have likely become digitigrade (making it hard to fit into most footwear), your arms have lengthened so you can run on all fours as needed, and, if your animal bond flies, you have grown wings. Conversely, if your animal bond relies on its hide or scales rather than mobility as a defense, you may have developed that defense for yourself.

In any case, your base walking speed is 40 feet, and you may triple your jumping distance (as if under the effect of the jump spell).

You gain one of the following abilities that is appropriate to your animal bond:

  • All Fours: When you are not carrying objects in either of your hands, your base walking speed is 60 feet.
  • Armor: You gain Unarmored Defense. While you are not wearing any armor, your Armor Class equals 10 + your Dexterity modifier + your Constitution modifier. You can use a shield and still gain this benefit. If you have Unarmored Defense as a class feature, you may add +1 AC to whichever source provides the better AC.
  • Wings: You have a fly speed equal to half your walking speed. You may not hover.

Due to an intensified fight or flight reflect, you have disadvantage on saving throws to resist becoming Frightened.

Ultimate Power: Hybrid

Finally, you have become a true optimal hybrid of the traits of humanoid and beast.

You gain advantage on saving throws against spells that specifically target humanoids or beasts but do not work on the other. Additionally, you gain advantage on saving throws against any kind of poison or disease transmitted from eating tainted food.

Your natural attack form increases by a die step in damage and counts as magical for penetrating damage resistance.

You gain one more beast ability from the base power and one more from the secondary power.

You are treated as always wearing cold weather gear.

It is now impossible to disguise your bestial nature without magic more powerful than disguise self (and even then, onlookers have advantage on checks to see through the disguise). At best, you can pretend to be a member of a similar-looking anthropomorphic race or transformed lycanthrope.
