They can also be bought as 'Item of the day' at Ammo Venders. Grenade mods are dropped by enemies, found in skag piles and chests, and can be given as mission rewards. They are named by their elemental property followed by their type, such as 'Explosive MIRV' or 'Incendiary Rain.' Each type of grenade mod is available in a range of different strengths that are roughly proportional to the level of the enemies encountered. Grenade Mods (short for Grenade Modification) are useful upgrades that modify the properties of a character's Protean Grenades by increasing their damage, changing their functionality, and/or adding elemental properties.
