S'kelt Nikor

The best written DND character and character in all of media, S’kelt is a character that everyone should strive to make in dnd. He’s perfect at literally everything and was a villain from the start of the campaign; just imagine DIO, but better.

Tyler: “Hey man what’re you playing in the new campaign?”
Aiden: “I think I’m gonna go for a S'kelt Nikor like character, a real badass!”
