<section begin="qiskullcavern" />After reading [[Secret Notes#Secret Note #10|Secret Note #10]], the player will find [[Mr. Qi]] at level 100 of the [[Skull Cavern]]. A cutscene ensues in which:
+
{{collapse|content=Mr. Qi will either congratulate the player for reaching level 100 without using [[Staircase]]s or say the player is "clever" but not "honorable" for using them. In either case, he will award the player with Iridium Snake Milk, which permanently increases the player's [[Health]] by 25 points.}}
{{History|1.3|Added Carbon Ghost, Iridium Bat, Iridium Crab, treasure rooms, and encounter with Mr. Qi. Removed exploit that allowed the player to avoid bomb damage by consuming food after placing a bomb.}}
