Slithering Strangulation
Effect. D4 rainbow-coloured ethereal boa constrictors emerge from the ground and capture one creature each for d8 rounds, dealing d2 damage each round. Attacking a constricted creature in melee comes with a 50% risk of the snake changing target to the attacker.
The scroll is found among the dirty rags in Ueth the Scalehunter's chamber — Ueth's gospel on one side, this Power on the other. It does not appear on the Bare Bones d10 table; it is unique to the Sepulchre and to the Strange Serpent Drug Cult whose visions birthed it. The constrictors are the colours nature forgot: jale, dolm, and ulfire, the same hues that bloom in the eye of someone bitten by an Emerald Serpent.

Whether the constrictors are summoned from nowhere or pulled out of the wielder's blood (Ueth's permanent venom-high) is left open. The Power's transcription as part of Ueth's gospel suggests a doctrinal use — sacrifice by snake — that the scenario never quite shows on the page.
