Maven's envoy and beacon.
First of all, you have to run cards until you meet that specific NPC, The envoy. This character's appearance is completely random, so you just need to run all the cards until this instance happens. After making contact with him several times (4-5), the Envoy will mention The Maven and she will observe you. By killing the boss on the map at this point, you'll notice that The Maven is actually looking at you. After defeating the Boss, Maven will give up " The Maven Beacon“, Which you must collect and it is a non-tradable quest item.
After doing all of the above which is the most difficult since it is totally RNG based, go back to your hideout and add the quest item you found Peripheral card. This will definitely improve your device, allowing you to summon the Maven in different maps.
Right after, browse one of our higher maps. A "Call Maven" button will appear, which you must click to let the Maven observe you. Complete the card to make him happy, for now. When you kill the boss of the map, a certain message appears on the map itself: “” This indicates that this map does not need to be completed again.
Doing all of the above will trigger your Atlas, which will show you which region you need to keep processing and killing the Bosses, to keep The Maven watching you. It takes 3 bosses to move on to the next stage, the Maven challenge. Killing the last of these 3 bosses will reward you with an invite. Pick it up and you can continue.
Maven's Crucible.
The invitation you chose is actually a map fragment that can be added to your map device. This will open 6 portals leading to Maven's Crucible. Jump into one of these and get ready for a treat.
Here is the most interesting part of all this ordeal you have endured. All the bosses you have defeated and captured previously are now ready to fight you here in this melting pot. The ultimate challenge of Echoes of The Atlas, this instance will really test your limits and skills.
If you manage to kill all of these monsters, the Gift of the Maven will be rewarded, a device that you can use to allocate points in your Atlas Passive Tree. Select what you want, confirm it and you are done with this adventure. Exit through the portal presented and you will be sent to your hiding place.
The entire Maven Trial literally redefines what it means to meet a boss, so be sure to prepare yourself accordingly. Gear up with the best gear you have, make sure you've practiced your build, and get ready to rumble with a host of powerful enemies. Please feel free to take a look at some great versions that we have featured on our website, to make things easier.
Hope this guide has saved you some time on how to find her at least, so good luck to the exiles.
