Love grenades in Starfinder. Everybody is a wizard with fireball! How about being able to return that back to whoever sent it your way?
Return to Sender (COMBAT)
If you swing just right, you can send what comes at you right back.
Benefit: As a reaction when a grenade is throw at you, you may make an melee attack. If your attack value equals or exceeds the attack value of the person throwing the grenade, you can return the grenade to the targets square where it explodes.
