You possess a unique capability to alter your form's composition in response to the environment or threats. This grants you a level of resilience and adaptability uncommon among other races.

Hardened Exterior:

When an opponent attempts an unarmed strike against you, your skin hardens on impact, causing the attacker to receive the damage they intended to inflict upon you.

Metallurgical Adaptation:

Your body can momentarily harden to a metallic state, granting you resistance to piercing, slashing, and bludgeoning damage. However, this metallic nature makes you more susceptible to Acid damage, taking double damage from such sources. Your unarmed strikes carry the weight and force of metal, dealing an additional 2d6 bludgeoning damage. 

Electrical Conduit:

Your adaptive nature allows you to act as a lightning rod, drawing in electrical energy from nearby sources. Any enemy lightning attack within 60 ft. of you is pulled towards you, regardless of the original target. Your body tries to channel and disperse the electrical energy, although it's not always to your benefit.
