Quantum-Entangled Medium Laser

The Quantum-Entangled Medium Laser fires a coherent quantum-entangled beam, which is quite heat-efficient for a considerable damage output.

However, half of the time it hits, the Laser does absolutely nothing.

Rumors
It was said it was part of a secret plot by The Society to make the weapons held by the Warrior Caste ineffective. It is unknown how the technology got to the Inner Sphere, where the weapon was constructed (as a series of prototypes) by Comstar.

Rules
Upon a successful hit, flip a coin or throw a d6. On half the cases (1-3 on the d6), the attack does nothing. (heat is still generated on the firing unit)

Additional rules
The QE Medium Laser (as all the family of Quantum-Entangled Lasers) is pre-nerfed and uses different fundamental physics to its cousins; thus it is immune to the laser nerfing extra rules when applicable. It also can't use the listed optional laser buffs.
