10 meters is too small and just the fact that it's a grenade makes me think it'll be difficult to apply damage. I think it should be a cluster of grenades that once thrown, grow wings like a swarm of insect-esque centidrones, following players and vehicles until they blow up with a 2000 blast radius and 100,000,000 damage, the weapon will be tactical area denial because the blasted area will burn for 10 minutes, the explosion explodes explosions with equal damage bonus of 203% against armor and shields and every time you die a kill cam infuriatingly shows your death over and over from multiple angles with dubstep playing in the background and a giant font appears on the screen that says "LOL GIT GUD SCRUB" until the end of match, but if all players are stuck, then the centidrones will dance and wait until you respawn and blow you up in your spawn as you spawn to respawn because risk vs reward sux, investment vs videogame poverty, make these cost aurum and strongbox loot with different colored drones, explosions, fire, and different dubstep songs and extra glitter for the font.
