You have exceptionally powerful ties to one of the elemental planes.

Prerequisite: Crysalin with the elemental affinity and element-infused racial traits.

Benefit: You gain an additional ability tied to your elemental affinity:

• Amphibious (Water): You gain the aquatic subtype and amphibious special quality.
• Breeze-kissed (Air): You are constantly surrounded with swirling winds, gaining a +2 racial bonus to AC against non-magical ranged attacks. You can calm or renew these winds as a swift action. Once per day, you can channel this wind into a single gust, making a bull rush or trip combat maneuver attempt against one creature within 30 feet. Whether or not the attempt succeeds, the winds are exhausted and no longer provide a bonus to your AC for 24 hours. This is a supernatural ability.
• Ferrous Growth (Earth): Once per day, you can cause a touched piece of non-magical iron or steel to grow into an object up to 10 pounds in weight, such as a sword, crowbar, or light steel shield. This object remains in this form for 10 minutes or until broken or destroyed, at which point it shrinks back to its original size and shape.
• Fire in the Blood (Fire): You gain fast healing 2 for 1 round anytime you take fire damage (whether or not this fire damage gets through any fire resistance you may have). You can heal up to 2 hit points per level per day with this ability, after which it ceases to function.

Special: A crysalin with this feat also counts as an ifrit, oread, sylph, or undine, depending on their elemental affinity (fire, earth, air, or water, respectively), for any effects related to race. For example, a crysalin with fire affinity is considered both a crysalin and an ifrit for the purpose of taking traits, feats, the effects of spells and magic items, and so on.
