As you may recall, Ingami, Dog Spirit (sentinel) and Irigami, Dog Spirit (gunner) were a 50-50 drop from the dog spirit souls from the Oni Eddie event a couple months back.

If you look through the drops for an Epic Gunner Soul, you'll see Irigami, Dog Spirit (gunner) listed right away as a possible drop. However, if you look through the possible drops from Epic Sentinel Souls, Ingami, Dog Spirit (sentinel) is conspicuously absent from the list of drops.

Does anyone know if this was intentional or if it's even accurate?
