When the item is used, it activates a massive laser attack similar to the Mewmewmew! attack, but far less damaging. However, it is still a massive amount of damage, and will hit everyone, including you and your pets. The damage can reach somewhere around 9000, so you might need contingency to survive the use. Added to the fact that it doesn't tell you the function when you get the item, you can be in an awful lot of trouble after this. (Note: As of Elona+ version 1.19, the laser no longer hits you.)
