Deckard's Journey in Diablo 4 Season 15 opens the way to Old Tristram, where a separate Butcher quest awards 5 Prime Ribs, enough to summon Moophisto once. The portal unlock and the material reward are different steps, so reaching Tristram alone does not complete the reward route. When planning resources, D4 Gold is a different resource from these quest-earned summoning materials.

How to Reach the Prime Rib Reward

Read all 10 of Deckard Cain's journals to unlock Deckard's Journey, then follow the quest back to the Imperial Library in Caldeum. Cain opens the Deckard's Memory portal, which leads to Old Tristram. You do not need Wirt's Lucky Coins or the Echo of Tristram encounter to pursue the Butcher reward.

In the upper-left part of Old Tristram, inspect the dead body to begin the hidden side quest. Speak with the townspeople and choose their Butcher dialogue options, then complete the objective to defeat him. The Burning Butcher at The Broiler in Gea Kul counts for this objective and provides a direct target without waiting for a random encounter. Completing the quest awards the 5 Prime Ribs. Treat this as a starting supply, not a repeatable farming loop.

Where to Spend the 5 Prime Ribs

Carry the Prime Ribs in your inventory and travel to the Altar of the Heifer east of Tyrael's Encampment. Interacting with this entrance altar takes you into the Bovine Sanctum without consuming the materials. Having the ribs ready therefore opens access before you commit them to the fight.

Activate the waypoint inside, then continue north to the arena's second Altar of the Heifer. This altar consumes 5 Prime Ribs and summons Moophisto, the Divine Bovine. The distinction matters: entering the area preserves your supply, while starting the boss encounter spends it.

Moophisto can drop Brisket of the Bovine, the cow-themed chest cosmetic. That is a possible reward from defeating the boss, not part of the guaranteed 5-rib quest payout. Receiving the summoning materials does not guarantee the cosmetic on your first defeat.

How to Get More Prime Ribs

The Cow King inside the Secret Cow Level is the farming target for additional Prime Ribs. Access to that dungeon is a separate requirement from unlocking Old Tristram, so the Butcher route can fund an initial summon without completing the cow-dungeon route first. For further attempts, work toward reaching the Cow King and collecting another set of 5 ribs.

Check your journal progress first, then choose between finishing the Tristram quest route and collecting more ribs from the Cow King. Before reviewing Diablo IV Items for sale for equipment planning, count the Prime Ribs you already hold and decide whether your next task is unlocking access or preparing another summon.
