Laser Turbine

It automatically flashes a screen wide horizontal laser beam when fully charged by attacks, damaging all enemies that are on the same level as the player. The beam is not stopped by walls.

The higher one's attack speed, the more attacks are required to charge the laser. This definitely includes permanent item effects (such as the Soldier's Syringe), but may or may not include temporary effects (such as Predatory Instincts or drops from Filial Imprinting). Furthermore, while it is possible to acquire enough Laser Turbines to fire after every attack at a given attack speed, the laser will not fire unless it has been more than ~0.6 seconds since it last fired.

The beam can be used to activate terrain interactive objects, such as buttons, cracked stone in the "artifact variants" of Dried Lake and Sky Meadows, and levers on Magma Barracks Sacrifice version.

This item was added in the v1.2 Patch.
