Aberrant Horrors are the result of a humanoid becoming an aberration. Able to break free from the physical restrictions imposed upon them by the Material Plane, they shift the components of their form at a whim. This makes Aberrant Horrors terrifying to behold, especially in battle. Many adversaries have been caught off-guard when a seemingly defenceless opponent grew rows of gruesome spines before their eyes.

Transformation level 1: Starting at 1st level, you gain the following Transformation Boons and this level’s Transformation Flaw.

Transformation Boon: Aberrant Adaptations Your body can twist and reshape itself as you will it, changing body parts into dangerous weapons or useful tools, and regenerating after damage. This ability is represented through Adaptations

Basic Adaptations At 1st level, you gain the following adaptations:

• Chitinous Shell. As a bonus action, you can develop a hard, crustacean-like shell. When you use this adaptation and are not wearing heavy armour, you gain a +2 to AC. However, this reduces your speed by 10 feet. This adaptation lasts for 1 minute or until you are knocked unconscious. On your turn, you may use a bonus action to end this Adaptation.
• Eldritch Limbs. You can transform one or both of your arms into a weapon of thick muscle, sharp claws, or hardened bone. When you make an attack, you can use this Adaptation. If you do, you gain the following features: • You can choose what type of damage your unarmed attacks will cause, from Piercing, Bludgeoning, or Slashing. Your arm becomes a claw, tusk, or bone club, depending on the damage type chosen. • You may roll a d6 in place of normal damage for unarmed strikes. • You cannot hold any object in the affected arm. This includes, but is not limited to, weapons, shields, and spellcasting focuses. Any object you are holding merges into your adaptation or immediately drops to the ground. The GM may decide if they feel the object is too large to merge. This adaptation lasts until you become knocked unconscious. On your turn, you may use a bonus action to end this adaptation.

Transformation Boon: Aberrant Form Your Constitution score increases by 2 and your Strength score increases by 1. An ability score cannot be increased beyond 16 this way.

Transformation Flaw: Unstable Mutations Your body becomes malleable and struggles to maintain any one physical shape. Upon completing a long rest, you must roll 1d100 on the Unstable Form table and apply the effects of the result, determined by your transformation level. These effects last until you complete another long rest. If you roll the same result on the table more than once in a row, roll again until a new result is rolled.
