I'm not sure what those buffs should be, but maybe you have some ideas? I think it's relatively okay, but maybe Scatter and Axion could use some functionality buffs

Chaos Accelerant buffs for each grenade: Vortex Grenade: in addition to the increased radius, at the end of its duration, it implodes (like the Warlock Prismatic Transcendent Grenade), dealing additional damage and applying Volatile to surrounding enemies. Axion Bolt: on impact, it applies a delayed Void explosion that damages and knocks back surrounding enemies. Scatter Grenades: doubles the submunitions, but rather than bouncing and exploding immediately, they scatter across the ground in a pool, and track to enemies in proximity. If no enemies are nearby to track to, they explode after about 5 seconds. Magnetic Grenades (Handheld Supernova): on release, the explosion is delayed. It pulls enemies in before detonation. Enemies damaged by the detonation have a second, delayed but weaker, explosion applied to them.
