Like an overgrown centipede with huge mandibles and a scorpion’s tail, its carapace is thick and black, while its tail is a rusty orange, topped with a three-pronged stinger.

Special Abilities
Triple Poison (Ex) The stinger of the centiochs is triple pronged with each prong housing a unique poison. When a centioch strikes with its stinger it can select any one of the following poisons to inject.

  • Maddening Sting—injury; save DC 22; frequency 1/round for 6 rounds; effect confusion (as the spell); cure 2 saves.
  • Paralysis Sting—injury; save DC 22; frequency 1/round for 6 rounds; effect paralysis; cure 2 consecutive saves.
  • Weakening Sting—injury; save DC 22; frequency 1/round for 6 rounds; effect 1d2 Con; cure 1 save

Centiochs scuttle through wet underground tunnels, devouring living creatures and carrion alike.
Centiochs live only a few years after hatching and leaving their colonies. They lay dozens of eggs at once, but fewer than one in six newborns survive to adulthood. Centiochs rarely eat creatures bigger than sheep, but large slow-moving or injured creatures may tempt centiochs into attacking anyway. Anger and hunger can also drive centiochs to attack. In combat, a centioch bites and stings one creature until that creature falls, then moves on to the next.

While a centioch’s poison becomes inert after the creature’s death, a character with the Craft (alchemy) skill can use it as a base for creating a poison equivalent to oil of taggit. A centioch’s stinger can be removed without need for a skill check. For purposes of determining creation time and raw materials cost, up to 10 doses of oil of taggit created with a centioch stinger cost only 45 gp each. Oil of taggit created in this manner has a Craft (alchemy) DC of 20. A character with 5 or more ranks in Knowledge (nature) has a +2 bonus on the Craft (alchemy) check.

On Porphyra
Centioch are a common nuisance in the Underdeep. Dromites have often attempted to control the centrioches with their psionic powers but have no uncovered a way to reach the vermin’s true mind, despite their own insectoid nature. Some of the troglodyte tribes that live in the Underdeep have worked to domestic the centioch so that they can be ridden into battle.
