Sneaking - IdleOn

January 26, 2026

Sneaking is a skill you can find in Spirited Valley where you must progress through several floors of the Dojo Tower with your IdleOn characters. Here you'll be able to earn the Jade currency, which is used to purchase items from the Jade Emporium, upgrade various Ninja abilities and also used in Alchemy.

Each character has their own Sneaking level, which is increased by them earning EXP passively during the game.

Sneaking Overview

Dojo Tower

To begin the Sneaking skill, click on the Dojo Tower in Spirited Valley (world 6).

Unlocking Ninjas

Each character becomes a Ninja in Sneaking. You start off with one, and slowly find the rest of your characters as you progress through the various floors.

Your other characters will be tied up on various floors within the tower.

You can find the rest of your characters on the following floors:

  • Floor 1 - Default
  • Floor 3
  • Floor 4
  • Floor 5 (2 characters)
  • Floor 6
  • Floor 7 (3 characters)
  • Floor 8

Floors

Floors

Dragging a Ninja onto an unlocked floor will allow them to perform a certain action depending on what item they have equipped. If you click on a Ninja, you'll be able to see their EXP rate per hour and Jade Coin rate per hour.

If they have the Kunai item equipped, they will begin untieing any Ninjas on that floor.

If they have the Nunchaku, they will deal damage to any locked doors. Breaking a door will unlock the floor above.

If they have Gloves equipped, they will increase their action speed, allowing you to find items and earn Jade faster.

Once a door is unlocked and there are no Ninjas to untie, you'll start being able to find items and earn Jade coins.

Each floor has it's own loot table that you can see in the top left corner of each floor. Any items that drop will appear in the bottom left corner for you to click on. You can then equip various items to your Ninjas via the Equipment tab inside the Sneaking interface.

Each floor also has it's own Detection rate. When you are detected, your Ninja's get knocked out and have to wait to be revived. Increasing your Ninja's stealth stat will help you avoid detection for longer, allowing them to farm items and Jade for longer.

Jade Coins can be spent on:

Once you reach the top of the tower, you'll be able to unlock Sneaking Mastery from The Rift. This allows you to restart from the bottom floor, but with increase Jade Coin rates, EXP and other bonuses.

Sneaking Upgrades - Ninja Knowledge

Ninja Knowledge is where you can spend any Jade Coins you have earned on various upgrades to improve Sneaking. You can access this by clicking on the tab on the left side of the Sneaking interface.

You can unlock "mini Ninja upgrades" from the Coral Reef in World 7.
