A Terror Vlish is a special variant of the standard Vlish. It has a special ability to invoke fear and terror in enemies causing them to flee from their attackers. In Geneforge 1 through 3 Terror Vlish were the upgraded version of Vlish, a magic creation. To upgrade any creation to its second form three points are needed in that creation and can be gained through a canisters or NPC trainers as well as a few books. Terror Vlish was replaced in Geneforge 4 and 5 with Charged Vlish which, in exchange for greater upfront firepower and health, deteriorates HP over time and will die after leaving an area.
