Tarball Launcher
The Tarball Launcher, also known as the Grenade Launcher or Tarball HRGL in the Codex, is Engineer's secondary weapon. It's a grenade launcher with sticky grenades that can be detonated remotely. Like all Secondary Weapons, it has limited ammo, and cannot be reloaded.
The Tarball Launcher's explosion also gives knockback, and unlike the Rocket Launcher or Sawed Off Shotgun, it's the explosion itself that gives the knockback. This lets the player shoot down and detonate immediately to gain momentum mid-air.
Being a secondary weapon, both the base weapon and the Weapon Mods can be leveled up, improving set stats a varying amount depending on the level, up to level 10. There are also rare and legendary variants of each Tarball Launcher & Tarball Launcher mod, each with a unique effect, and the legendary variant gives both the rare and legendary effect for that weapon.
The Rare Effect does not retain the damage bonus after a bounce once it sticks to an enemy.
Note that the effects of rarity modifiers are not reflected in the stats section, only the rarity modifiers section.
