Rude Wand

The Rude Wand is a craftable Hardmode sentry summon weapon. It summons one of four floating Delta Totems: the Pulse Totem, the Laser Totem, the Buster Totem, and the Spread Totem. Each of these Delta Totems use a unique attack to damage enemies. The player can alternate between the four Delta Totems by right-clicking; the display below the player will show which Delta Totem will be called.

Trivia

 * This item is a reference to the  fangame Undertale Red. The Delta Totems' attack types are based on the various attacks used by the boss Red.
