History of Buildcrafter

Buildcrafter is a 25-point triumph: complete playlist or seasonal activities using each Light subclass (Arc, Solar and Void). Search-result summaries say it was added in Season 19 and expires at the end of Season of the Wish; I could not open a page that confirms this (light.gg returns 403).

How to complete

Unconfirmed beyond the game text. Reasonable approach: finish a playlist or seasonal activity once on each Light subclass, tracking it in the Triumphs menu. It is not part of the Wishbearer seal, per an article I opened listing that seal.
