Quick Guide
- The Grubnik the Goblin Chief Bestiary lists one Bone Sword Blueprint at 8%. A separate boss victory reward screen also shows the blueprint; that screen does not identify Grubnik as its encounter. The reward screen is one captured victory sample, not a promise that every boss drops this blueprint.
One run’s rewards include currency, experience, pet XP and loot cards. They are not guaranteed drops.
