Berserk Turrets appear as red Shadows in the second and third sections of Antenora within the Abyss of Time. They will be in a group of five small tanks when encountered. They can also be hard to damage with attacks to both their weakness and the elements they don't have a defense against, even from party members that have a much higher level than them. The party can either elect to use multi-_target Elec, Ice, and Wind skills to damage them or try to focus on one at a time to knock them out of the fight.
In Golden, they appear in Paths 4, 5 and 8, and can also be summoned by Brilliant Kings. They have single-_target spells of all four elements, Megidolaon, and Mind Charge.
