Terraria (Wiki): Rainbow Gun


Everything you need to know

General Information

The Rainbow Gun delivers what the user wants -- fire a deadly rainbow. This unique magic weapon creates a straight line that will curve downwards, lasting for 40s (desktop, mobile, console) / 10s (3DS, old-gen consoles) or once a new rainbow is fired.    During combat, the Rainbow Gun damages enemies 5x/s, making it ideal against segmented enemies or bosses, invasions, and other huge waves where single-targeting weapons usually fall short. The lasting knockback effect also effectively freezes enemies caught on the rainbow.   Using the Ruthless modifier is best for maximizing the Rainbow Gun's efficiency, as it benefits damage output the most. Stellar Tune and Staff of Earth also complement the Rainbow Gun by providing an increased critical strike chance.
