The Elite Tesla Coil is a defensive weapon used by the Crimson Empire. It has 1 range, 12 attack and 25 life.
The Elite Tesla Coil is first encountered midway through Nordurland. There are a trio of them guarding a nearby Maximum security Prison on an island that isn't connected to the rest of Nordurland. As to why there would be on an island that isn't connected to the rest of Nordurland remains to be seen.
