n Path of Exile, the number of scarabs you can use in a map depends on the upgrade level of your Map Device:
Base Level (Up to 3 Scarabs): By default, you can place up to three scarabs in the Map Device before running a map.
Upgraded Map Device (Up to 4 Scarabs): Upgrading your Map Device through specific Atlas passives allows you to use an additional scarab, bringing the total to four scarabs per map.
Here’s a quick breakdown:
| Map Device Level | Maximum Usable Scarabs | 
|---|---|
| Base Level | 3 | 
| Upgraded (Atlas Passives) | 4 | 
Important Note:
There are no scarabs that directly increase the number of usable scarabs per map.
Using sextants alongside scarabs is a common strategy for further map modification. However, sextants don’t affect the number of scarabs you can use.
