All Battleground Missions

All Battleground Missions is a Season of the Chosen triumph required for the Chosen seal. Complete each Battleground activity at least once.

How to complete

1. Finish one run of every Battleground. Completions can come from the Battlegrounds playlist or from the individual mission.
2. The four are Behemoth (Nessus, boss outside a Cabal tank fortress), Hailstone (Europa), Foothold (Cosmodrome) and Oracle (Nessus, underground Psion boss).
3. The playlist rotates, so queue it repeatedly until all four are checked off. Only one completion per Battleground is needed.

Notes

Reported point values range from 15 to 25, and reports differ on whether the fourth Battleground is Foothold or Cleansing.
