Stamps Guide - IdleOn

Stamps are items that can be upgraded in IdleOn to give various stat increases and bonuses. You can unlock stamps starting in World 1 by speaking to Mr. Pigibank.

• How Do Stamps Work
• All Stamps
• Stamp Bribes
• Special Stamp Bonuses

To get started with Stamps, you need to reach Level 14 and speak to Mr. Pigibank in the World 1 Town Map. Here you can deposit any Stamp items you find and then upgrade them.

Upgrading Stamps starts out slow, but can offer some of the biggest boosts to your characters in IdleOn and is definitely worth investing significant resources to upgrade them.

How Do Stamps Work

Stamps can come from many different sources in IdleOn, including dropping from Monsters, purchasable from Vendors and Quest Rewards.

Once you have a Stamp in your Inventory, take it to Mr. Pigibank who will automatically collect it and unlock the Level 1 bonus for that Stamp. Only one Stamp item is needed to unlock it, so you can throw away any multiple copies you may find.

Each Stamp can then be upgraded using coins. At various Level brackets, you'll need to give materials/items to upgrade a Stamp further.

You can also unlock Bribes from Mr. Pigibank (see below), which give additional bonuses to every character on your account. Each Bribe costs a certain amount of coins to unlock.

All Stamps

Stamps are broken down into three categories: Combat, Skills and Misc.

They have no max level, but are soft-capped by how many items you can hold in your Inventory when trying to upgrade them.
