For everyone gasping in shock at the moment, it's a lot less fancy than the name suggests.
A laser is just basically a beam of concentrated energy-mine are not. They're just massive explosions pointed in the general direction of the baddies.

I won't say how I do this yet, it's not very fancy though so don't expect much WOW factor
My current ones can slice through armour, lava and water but they aren't very focused-when i tried it just did the same damage in a smaller area.

So yeah, legomax, it's a good day to surrender
these aren't even the full Particle Conglomeration Lasers (they're pretty fun) and look what they do
