Change Shape (Su): A rukarazyll can assume the form of any Medium humanoid.

Spell-Like Abilities (Sp): At will - blur, darkness, desecrate, detect good, detect magic, mirror image, cat's grace, telekinesis, entangle, plant growth, protection from good, undetectable alignment, snare, and teleport without error (self plus 50 pounds of objects only); 3/day - unhallow, unholy blight; 1/day - wall of thorns, command plants, heal. These abilities are as the spells cast by a 12th-level sorcerer.

Spit Ooze (Su): Once every 10 minutes, the rukarazyll can expel a Medium-size gray ooze from its mouth at any one target as a grenade-like weapon with a 10-foot range increment. If the target is hit, the gray ooze can immediately attempt to use its improved grab ability and start constricting the victim on the following round. If the spat ooze misses, determine miss distance and direction normally. The ooze moves to attack normally the next round. Gray oozes created in this manner are short lived; after 2d4 rounds of life, such oozes die.

Fungus (Su): A living creature struck by a rukarazyll's melee attacks must make a Fortitude saving throw (DC 20) or become infested with the fecund fungus that grows on the creature's body. This fungus grows rapidly when introduced to living tissue. This growth causes no damage, but it feels quite unpleasant and infests a Medium-sized creature in 1d4 rounds. Each size category larger increases the growth time by 1d4 rounds; creatures smaller than Medium-size are infested in 1 round. Creatures can free themselves of the fungus before they are infested by being subject to 10 points of fire or cold damage, or a remove disease spell. Once infested, the fibrous white filaments begin to seethe and twist, actively trying to resist any actions the infested creature attempts. This incurs a -2 penalty to all attack rolls, Dexterity-based skill checks, and Reflex saving throws. In addition, the fungus continues to grow in the victim's body (albeit at a much slower rate), slowly eating away at his personality at the rate of one point of permanent Charisma drain per day. Once the victim's Charisma reaches zero, he dies and transforms into an immobile heap of fungus that lives for an additional 3d6 weeks before perishing. A remove disease spell destroyed the infestation, but not the Charisma drain.

It is possible to become infested by coming into contact with one of these transformed bodies; infestation can be resisted with a successful Fortitude saving throw (DC 16).

Evasion (Ex): A rukarazyll can avoid even magical and unusual attacks with great agility. If it makes a successful Reflex saving throw against an attack that normally deals half damage on a successful save, the rukarazyll instead takes no damage.

Profane Alacrity (Su): The rukarazyll is infused with a unholy energy that grants it amazing reflexes and speed. These unholy energies actively work to block and turn aside incoming attacks (granting a +3 profane bonus to the rukarazyll's Armor Class) and also allow the rukarazyll to take 10 on any Balance, Escape Artist , and Tumble checks in any circumstance. Once per hour, the rukarazyll can call upon these energies to gain a temporary boost to its movement, doubling its speed and profane bonus to Armor Class for 1 minute. After this minute, the rukarazyll's profane energies are depleted for 1 hour, during which time it does not receive the bonus to AC or the ability to take 10 in any circumstance.
