Details
This is the only Brutality-scaling shield in the game. Its blueprint can be found in a secret area in the Ancient Sewers, hidden under a pool of poisonous water. The blueprint can either be accessed by diving through the pool of water, at the risk of taking damage, or by using the Homunculus rune to reach it.
