Power packs

Firing chambers
This item can broaden the beam of certain blaster types, increasing damage or possibly granting other effects. The modifications require a workbench and a weapon of high quality marked as upgradeable.

Mandalorian Chamber
Unlike the first two Marks, Mark III has an Enhancement Bonus rather than just an Attack Bonus, granting Attack Modifier: +1 and Damage Bonus: 1 of the same type as the weapon itself for 3-17 (2d8 +1) in total.
