The Insanity Badge in EToH appears to be a secret/challenge badge tied to a multi-stage puzzle or special event , rather than a normal tower-clear reward. One source describes it as a harder badge unlocked after the Lights Badge, involving environmental clues, patterns, and a final completion trigger.

What it likely means

  • It is not just a standard “beat a tower” badge.
  • It seems to require solving a hidden sequence or navigating a special area.
  • The badge is awarded once the full puzzle chain is completed.

Practical takeaway

A guide-style source says to:

  • Watch for visual anomalies and interactive elements.
  • Record any codes, numbers, or patterns you see.
  • Use those clues to advance through each stage.
  • Rejoin the game if the puzzle asks you to.

One important note

There is also a separate EToH badge wiki entry showing that badges in EToH can come from towers, realms, events, or secrets, so “Insanity Badge” fits the general pattern of a special unlock rather than a standard completion badge.

If you want the exact how to get it steps for the EToH version, I can give you a clean guide based on the available references.
