Pro tip: don't charge the attack, just spam it if you fight anything below level 100.

This simple 2 Forma (3 if you have maxed [Hornet Strike]+[Magnum Force]) baby has been the trusted companion of our Clan's players for years.

Corrossive+Radiation+Blast make it effective against all enemy types in the game. If you are leveling a primary weapon, just equip this and blast your way through anything by spamming the enemy down.

Only downsides are that it requires aiming against flying enemies and single target damage falls off compared to powerful primaries in the lategame.
