This best stamp guide details how to optimise your stamp progression for account wide damage, skilling and utility bonuses. This page includes an exalted stamp priority list, tips to maximise stamps and where to find key stamp bonuses to multiply their boosts.
Stamps are a critical upgrade mechanic in World 1 which scale the Wizard damage per stamp collected and after obtaining the World 6 Wind Walker can be exalted to double their bonus. For details of all stamps, the upgrade material and source refer to the Idleon stamp wiki page.

Best Stamps – Exalted Priority List
This stamp tier list is to prioritise obtaining, upgrading and eventually exalting as these provide either large bonuses or a rare account boosts. As Exalted stamp upgrades are limited these should be saved until you have access to these stamps while considering your own account progression. I also recommend saving some Exalted upgrades for future world releases.

Stamp Progress Optimisation Tips
- Always Upgrade Stamps: While stamps are a World 1 mechanic and provide seemingly small bonuses its important to upgrade them as there are stamp multipliers later in progression and overall stamp level is a factor in other mechanics.
- Rift Stamp Levels (Gilded Stamps): Overall stamp level impacts your chance to get a Gilded Stamp (95% cost reduction) daily from the World 4 Rift 26. 10,000 total stamp level is a useful milestone as it guarantees one daily so remember to collect all stamps and even level the weaker ones.
- Stamp Reduction: Hydrogen bonus and Gilded Stamps are automatically used so don’t waste these on stamps you don’t need the material reduction cost on.
- Carry Capacity Increase: Capacity and money are the limiting factors of higher stamp levels. Permanent and temporary carry capacity increases are available to overcome these limits combined with expanding your overall inventory.
- No Stamp Left Behind (NSLB): This mechanic triggers on each daily login and selects a stamp randomly to increase in level. With luck this can overcome capacity limitations and reach stamp levels not possible otherwise.
