Fargo's Mod/Twinrangs

Twinrangs is a Hardmode boomerang dropped by The Twins. It fires a different boomerang depending on the mouse click. Left-clicking throws a fast Spazmrang, which spews long Cursed Flames in a ring upon hitting an enemy or tile. Right-clicking throws a slower Retirang that doesn't deal damage, which stays still in its place then shoots 3 damaging lasers in the cursor's direction from it.

Its best modifier is Godly.
