How Demon Born Clan Spins Work

Demon Born features 57 clans divided into four tiers: S (3 clans), A (3 clans), B (2 clans), and 49 buffless common clans. Every time you use a clan spin, the game randomly selects one of these 57 clans with equal probability.

This means each spin has a 3 in 57 (5.26%) chance of landing an S-tier clan like Hayakawa, Kishimoto, or Kishibe. With 10 spins, you have about a 42% chance of getting at least one S-tier. To reach 90% confidence, you'd need around 43 spins.
