The effects of the tentacles, from Arcanolypse Now.
A spell employed by Vaarsuvius in The Dungeon of Dorukan to defeat the chimera Trigak. It is a fictitious spell, based off Evard's Black Tentacles. According to The Giant, he was looking for the most painful sounding name for a spell.[1] He also later stated that he regrets this joke, due to its connotations of rape.[2]
In April the 23rd, 2015 it was revealed that the use of a Conjuration spell is retroactively impossible for Vaarsuvius, and therefore it is assumed that they used Shadow Conjuration instead, with the characters around failing their saving throws.[3]
