Stoneoak Tower Shield can also drop from the chest. It is not purchasable from the tier 1 raid merchant until you get the achievement Vanquisher of Saving Jacyll:
- Spelling Bee
- Drum Solo
- Honey Don't
This also unlocks the Bloodstained Shoulders if you haven't gotten that achievement yet from the lower raids.
