Eifelian Mutations

The following is a list of mutations available to Eifelians. Each mutation costs 1 mutation point and, unless otherwise stated, cannot be selected more than once.

---

Acid Spit: The stomach of the Eifelian generates intense acid capable of severely damaging foes. Once per day as a standard action, the Eifelian may regurgitate their stomach contents in a 15-foot cone. Anyone caught in the cone takes 1d6+Constitution modifier+HD acid damage (successful Reflex save DC 10+1/2 level+Constitution modifier negates damage). Taking this mutation additional times allows the Eifelian to choose one of the following bonuses:

• Extra Spit: The Eifelian may use this ability an additional time per day. This bonus may be selected multiple times.
• Increased Area: Increase the area of this ability to a 30-foot cone.
• Increased Damage: Increase the damage of this ability by 1d6. This bonus may be selected multiple times.
• Powerful Spit: This ability deals half damage on a successful saving throw.

Bioluminescence: The Eifelian's body generates glowing chemicals used to light up the world around it. The Eifelian can control the intensity of their light from no light at all, up to the intensity and functionality of a hooded lantern.
Bite: The Eifelian has shark-like or angler-like teeth capable of tearing their enemy's flesh. The Eifelian gains a primary bite attack that deals damage appropriate to their size (1d6 for medium). Taking this mutation a second time increases the base damage of the bite to 1d8.
Chromatophores: Small pigment-filled cells line the Eifelian's skin and allow them to change their skin's color and texture to better blend in with their environment. As a standard action that doesn't provoke attacks of opportunity, the Eifelian can gain the benefits of Blend With Surroundings. This ability only works in natural environments and when the Eifelian is adjacent to some kind of object (ie it cannot be used in open air or water). Additionally, this ability only changes the appearance of the Eifelian, not any objects they're carrying or wearing.

Claws: The Eifelian has long claws used to slice the bodies of their foes. The Eifelian gains two primary claw attacks that deal damage appropriate for their size (1d4 for medium). Taking this mutation a second time increases the base damage of the claws to 1d6.
Darkvision: The Eifelian gains darkvision out to 60 feet. Taking this mutation a second time increases the range to 90 feet.
Echolocation: The Eifelian gains blindsense out to 30 feet, but only while completely underwater.
Electrocytes: The Eifelian's body contains Electrocytes, cells responsible for generating vast amounts of electric charge. Once per day, as a swift action, the Eifelian may release this built up charge. Unarmed strikes, natural attacks, and weapon attacks made with weapons made of conductive material deal an additional 1d6+Constitution modifier electricity damage. This bonus lasts for a number of rounds equal to the Eifelian's character level. The Eifelian may end the effects of this ability at any time as a free action.
Extremophile: The Eifelian's DNA has been combined with some of the most resilient creatures in the sea. They are constantly under the effects of Endure Elements and become immune to pressure and geopoisons.
Fast Swimmer: The Eifelian has increased swimming capabilities. They increase their swim speed by 10 feet. This ability may be selected multiple times.
Grappling Appendages: The Eifelian has additional limbs meant for grappling. The Eifelian gains Improved Grapple as a bonus feat and can grapple and still make attacks with their main appendages. These limbs aren't capable of movements fine enough to finely manipulate objects and thus, can't be used to wield weapons or shields. They're capable of holding objects, but not retrieving them from storage on the Eifelian's body.
Ink Sacs: The Eifelian's body produces thick slimy ink made of mucus and melanin. Once per hour as a standard action, the Eifelian can emit a 10-foot radius sphere of ink while underwater. This ink is centered on the Eifelian. The ink provides total concealment and persists for 1 minute.
Jet: The Eifelian is capable of rapidly retreating from danger. The Eifelian can swim 200 feet backward as a full-round action. The Eifelian must move in a straight line when doing this and doesn't provoke attacks of opportunity when using their jet.
Natural Armor: The Eifelian is covered in scales or armor that makes them more resistant to damage. They gain a +1 natural armor bonus to AC. This ability may be selected twice, increasing the bonus to +2 instead of +1.
Regeneration: The Eifelian's body is capable of miraculous acts of healing. An Eifelian with this ability can regrow severed or destroyed limbs, tentacles, tendrils, etc. in 3d4 weeks without the aid of magical healing. Magical healing that doesn't convey regeneration or the ability to regrow limbs doesn't affect this ability.
Spines: The Eifelian is covered with prickly spines that contain venom. Any creature that makes a successful unarmed or natural attack against the Eifelian takes one point of piercing damage and one point of Dexterity damage. The Dexterity damage is cumulative and wears off, all at once, three rounds after the last point of Dexterity damage was received.
