Build role and upgrade context
Role: Late status finisher. Collect it after Sariel and treat it as an endgame option for builds that already understand Resolve timing and status upkeep.
Pairing: Sariel or Genessa / use recovery or summons to create safe shots. Sidearms share the Obsidian Lathe upgrade path, so record the route before spending scarce materials.
