History of Champion's Rite

A Season of the Chosen triumph: defeat Champions in Battlegrounds while wearing Season of the Chosen seasonal armor (the Praefectus set).

How to complete

1. Obtain the Praefectus armor and equip a full set (search results suggest 4-5 pieces; an Exotic with four seasonal pieces reportedly works, partial sets do not).
2. Run Battlegrounds and kill Champions in them. Bring Anti-Champion mods, since each Champion type needs a counter.
3. Check the in-game tracker progress.

Notes

The Shacknews guide lists the triumph under Gear for the Chosen title; the armor-piece count comes from a search summary and is unconfirmed. Seasonal content has since rotated; current availability is unverified.
