In Elden Ring, the Spellproof Pickled Liver has seen some recent developments.

Functionally, its effectiveness against spells might have been adjusted. It could now offer more protection against a broader range of magical attacks. For example, it may be more resilient against both sorceries and incantations that previously bypassed its spell – resistant properties.
From a gameplay balance perspective, the acquisition or crafting requirements of the Spellproof Pickled Liver could have been altered. This ensures that it fits better within the overall balance of the game’s economy and item rarity system.

These updates contribute to the continuous evolution of the gameplay experience in Elden Ring.
