Starfarer's Arsenal: Laser Grenades

From publisher blurb: SOMETIMES YOU WANT A GRENADE YOU CAN USE AGAIN, AND AGAIN, AND AGAIN ... The Starfarer’s Arsenal is a line of short pdfs offering a single weapon, from item level 1-20. No matter what level your character is, there’s a weapon at just the level they want in the Starfarer’s Arsenal! Laser grenades are an unusual blend of laser technology and the tactical area-denial function of grenades and other explosives. Rather than destroy itself with each use, a laser grenade flash-dumps a batter charge to create a burst of laser damage in an area. Though expended, the laser grenade can be recovered, loaded with a new battery, and used again.
