Laser is a dummied alchemy formula not implemented in the final product. It can only be accessed by hacking the game.
Laser was not fully implemented in the final product: it uses the same menu icon as Levitate and the same animation as Acid Rain. Laser was intended to halve an enemy's HP, but in its unfinished form only does a single point of damage.
