Cartographer’s Sextant Mods & Guide 3.7: Apprentice, Journeyman, Master

Cartographer’s Sextants are used on the Atlas of Worlds to add a random mod to a map. This effect has a radius on the Atlas, so any map with a sextant mod can apply that mod to other nearby maps on the Atlas within a certain range.

PoE Sextant Limit

Sextant mods applied to the Atlas last a total of 3 uses of maps within the radius.

+1 Maximum Sextants for completing all bonus objectives on yellow Maps.
+1 Maximum Sextants for completing all bonus objectives on Red Maps.
+1 Maximum Sextants for completing all of Zana’s quests

Each sextant will have 3 map uses. 1 use of a Sextant is consumed per map opened in the map device that is within that sextant red circle, no completion or entrance of the map required. So you will get 3 map creations before you need to re-apply sextants. Adding a Sextant Beyond your Maximum will remove your oldest Sextant.

The number of sextants allowed is effectively tied to your Atlas Completion Bonus Objectives. Within that counter, it will show you your oldest sextant that will be removed if a sextant is applied past your limit to a map base without a sextant. Maps that currently have sextants can just be re-rolled without having the oldest removed if you are at the limit.

Sextants three variants

An Apprentice Cartographer’s Sextant can only be applied on a map up to Map Tier 5. A Journeyman Cartographer’s Sextant can only be applied on a map up to Map Tier 10. A Master Cartographer’s Sextant can be applied on any map. The matching tiers can be recognized by the color or name:

Cartographer’s Sextant	Maps Tier
Apprentice Cartographer’s Sextant	Low-tier maps (Tier 1 to 5)
Journeyman Cartographer’s Sextant	Mid-tier maps (Tier 1 to 10)
Master Cartographer’s Sextant	Top-tier maps (Tier 1 to 16)

Cartographer’s Sextant Strategy

The best way to make use of sextants, is to apply them on and around a certain map base that you will be running numerous times (generally a minimum of 3). For the most part, players chose to do this on maps they have shaped or that are above tier 11. It is important to note, that sextants affecting the same maps are unable to roll the same modifiers. This was originally used to create massive Sextant Blocks, but now due to the Sextant Limit on the Atlas, you are only able to do this at a small scale. This makes this strategy useful to minimize the cost of re-rolling your sextants as they can be used to block bad modifiers.So when you are applying your Sextants at and around your chosen map base, you will want to use the cheaper sextants first, moving up into the more expensive ones until you hit your sextant limit or number applicable modifiable maps available.

This usually results in rolling the poor modifiers first on the cheaper sextants, blocking the chance of getting bad modifiers on the more expensive sextants. You can then go back and re-roll them in the reverse order to get them to valuable modifiers, hopefully minimizing the re-roll cost.

After these sextants have been applied, you can simply use a map base within the sextant modification area to activate and use those sextant modifiers!
