— Ingame description
Apart from three cases, a Wrath Core is obtained by gathering four Wrath Shards. In other words, each fourth Wrath Shard found will complete one full Wrath Core and add one bar to War's Wrath Meter. There is a total of nine Wrath Cores to be gathered, six of which are made from collecting Wrath Shards and three are obtained as a full Core.
Full Wrath Cores can be obtained only three times in the entire game:
- One can be purchased from Vulgrim for 10,000 Currency Souls.
- Vulgrim gives War a Wrath Core after bringing him Overlord Artifact.
- There is a small area below the chest containing an Abyssal Armor piece in the Twilight Cathedral. Jump down into this area to find two chests. The one closest to the lava contains a Wrath Core
