Getting 6th scarab slot

I have done several T17 maps, but no 6th slot?

Can I not do it this way? I was lead to believe I could?

I think it mentions how to get it in the patch notes. I cant remember what it was exactly, but fairly certain t17 is for the 6th, the other one was earlier on, so people had access to the 5th before completing t17, but I can't remember what it was exactly.

What im wondering is maybe you got the t17 already and didnt get what ever the other one was? Unless you know what that one is and already have it?

Just read another post mentioning that it is Maven for one of the slots, which i think is correct. Did you complete Maven yet?

From the Patch Notes:

Added a 6th slot to the Map Device. The 5th Map Device slot is now unlocked by completing either Maven's Invitation: The Atlas, or by completing a non-Valdo's Tier 17 Map. The 6th slot is unlocked when you complete the other encounter.

Thanks xjjanie. So its completing the 10 way, not Maven herself. Guessing op you did a t17 but not the 10 way?

I can confirm, doing a maven invite got me my 6th slot!

To recapitulate...do Maven invite, get 5th slot, do t17 map solo or party, get 6th slot.

Thanks all!
