D&D Helper

Description

This silver handled butterfly knife has a refined cobalt blade. Every time the knife is opened, the blade shows a different color. As a bonus action, the wielder can showfully flip the knife closed and open in order to change the color. When the wielder hits on their attack, the knife deals normal damage plus an additional effect based on the color of the blade.

Distractingly Dazzling Don Armor: Once per day, as a bonus action, you twirl the knife and pose. Everyone who can see you must make a DC 16 Charisma Saving Throw. On a failed save they are stunned and time is slowed to watch you. Your arcane servants dress you in armor like a magical girl.

See Invisibility: While wielding the knife, you see invisible creatures and objects as if they were ghostly and translucent.; you suffer no ill effects when targeting an invisible creature.
