Farming ancestral and mythic unique gear in Diablo 4 Season 15 works best when you stop treating every drop as a lottery. Belial, Lord of Lies, gives each run a clear purpose because his reward hoard lets you aim at another lair boss. That matters once Torment tiers start taking real time. With the right pace, D4 items become a target you can work towards rather than something you hope to stumble across. The route is simple: build keys, run lesser bosses, then spend the reward key only when the chosen pool suits your build.
Build the Key Supply First
Before entering the palace, build standard Lair Keys through Helltide events and Tortured Gifts. Seasonal journey rewards may add a Lair Key Ring. Spend the keys on early Lair Bosses such as the Beast in the Ice, Grigoire, or Lord Zir. Their hoards can call in a weaker Belial ambush. Defeat it to earn a Superior Lair Key, the currency for Belial's own hoard. Keep several standard keys ready so one lucky ambush does not end the session.
Choose the Reward Pool with Care
With Superior Lair Keys ready, head to the Palace of the Deceiver in Amber Sands, west of the Tarsarak Waypoint. On Torment I or higher, use the altar to begin. The encounter costs no key, so you can learn the claw swipes, poison pools, and tracking waves without spending saved currency. After the kill, Belial's personal Lair Boss Hoard appears. One Superior Lair Key opens it, and its reward screen lets you select another Lair Boss's pool. Choose the pool that matches the unique your build needs; repeating a focused choice is more useful than chasing several targets at once. Each run can also bring an ancestral unique or a stronger affix.
Prepare for a Clean Kill
Your setup decides how many runs fit into an evening. Use poison resistance, keep enough movement to leave danger zones, and bring damage that can break the stagger bar quickly. Watch the floor and move before hazards overlap. Do not chase a low-health boss through a poison pool. In a group, decide who revives and who holds attention. Solo players may prefer a forgiving build over fragile burst damage. The fight is free to start, but the hoard key remains valuable, so steady execution beats reckless speed.
Key Comparison and Session Rhythm
For a quick comparison, standard Lair Keys come from Helltide rewards and lesser hoards, while Superior Lair Keys come from Belial ambushes and open his selected hoard. A repeatable session runs Helltide, lesser boss, ambush, Belial, then the chosen reward pool. If clear speed falls, adjust the build or pause instead of forcing another attempt. You will gain more from a route you can repeat calmly, and it works well alongside cheap D4 items when you are filling the remaining gaps in a build.
