Collected a Pioneer armor set
For this achievement you need a full set of pioneer gear (helm, chest, arms & boots) you will not need the rings.
first you must reach level 70 (max level) then unlock chult. Next you need 11,000 Chultan Riches
Chultan Riches drop from almost anything you do in Chult! HE's, fishing, Quests, and other miscellaneous stuff. 7 from running TONG. If you are a lower item level player then I would just fish for them, Now if you are a higher item level player and have good team to farm TONG then you can get about 1k Chultan Riches each run (12 -45 minutes per run depending on team) This video will show you how to get the Pioneer gear, till next time stay Frosty!
