Fastball

root@tediore-db:~$ cat description.txt

A Tediore grenade built like a thrown projectile weapon, travelling in a shallow arc at extreme speed. It has no fuse and detonates instantly when it hits an enemy or destructible object, making it one of the best options for deleting a single target at range. If it strikes an inert surface it will bounce instead, and its tiny blast radius keeps the damage tightly focused.

It pairs especially well with Moxxi healing weapons such as the Grog Nozzle or Rubi, since its massive impact damage converts into an immediate burst of healing. In Ultimate Vault Hunter Mode, slag pushes that damage even higher, which makes it especially effective against large enemies, raid bosses, and Krieg setups built around Bloodsplosion.

There is also a known bug where its damage can drop after loading in with it equipped. Re-equipping the grenade restores the correct value.
