Rudinn is a Darkner enemy encountered in the Card Kingdom in Deltarune. First appearing in the Field, Rudinn is a diamond-themed character, resembling a slug with diamond motifs and wielding a diamond-shaped dagger. Despite being ordered to fight by King, Rudinn shows little enthusiasm for battle and can be easily convinced to stop fighting, especially if tempted by riches or jewels, which they greatly value. Rudinns are more interested in wealth than their job, often speaking about money and trading their beds for jewelry. They appear throughout the Card Kingdom as NPCs and in battles alongside other enemies like Hathy and Jigsawry. Players can spare Rudinn through various methods, such as convincing them or using specific items like the Glowshard. For fans of Deltarune, a game fanart cursor featuring Rudinn and their iconic dagger is a perfect way to bring a piece of the Card Kingdom to your digital space, capturing the unique and quirky design of this diamond-loving character.
