Mythic Unique hunting in Diablo IV has gradually become less about blind luck and more about building toward a guaranteed finish. That matters for Heir of Perdition more than almost any other helm. In Season of Infernal Chaos, the best way to get it is not to pray for one perfect boss drop first. The most reliable plan is to farm content that can still drop Mythic Uniques, gather the required runes and Sparks, and then craft Heir of Perdition at the Jeweler.
If you searched for Héritier de perdition, that is the same item as Heir of Perdition. It is not a separate seasonal helm. What changes from season to season is usually the best farming route, the boss terminology, and how efficient direct drops feel compared with crafting.
Heir of Perdition is a class-agnostic Mythic Unique helm, which is why it shows up in so many endgame wish lists. Public item databases consistently describe it as a highly offensive piece built around a major damage effect, commonly listed as Mother’s Favor or Lilith’s Favor. Those appear to be localization or naming variants for the same unique effect, not two different helms.
That combination is why players chase it so hard: it is generic enough to fit many builds, but powerful enough to feel like a real endgame upgrade. The catch is that it sits in the Mythic Unique tier, so the direct drop is still rare.
The most dependable route currently reported across public guides is the Jeweler recipe. Instead of hoping the exact helm drops, you work toward the item with materials that can be farmed over time. Open Town → Jeweler → Mythic Unique Crafting and check the recipe directly in your current season interface.
This is the method to prioritize because it removes the worst part of the Mythic grind: needing the game to roll one specific item. Even if direct drops stay unlucky, every useful rune and every Spark you add moves you closer to the helmet. On console and PC, the acquisition method is the same; the only real difference is how you tab through the Jeweler menus.

The smart route is hybrid farming. Do not separate “drop farming” and “craft farming” into two different grinds. Run content that can do both jobs at once: give you a chance at Mythic drops while also feeding your rune and Spark progress.
That last point saves a lot of wasted time. Once the materials are complete, crafting is the finish line. Continuing to chase a low-probability direct drop only makes sense if you are also targeting other Mythics from the same loop.
Yes, but this is where the public information gets messy. Some widely used database-style sources say Mythic Uniques can drop from boss encounters in Torment I+. Some newer guides frame the best route around Lair bosses or higher-end boss tiers, especially on stronger difficulty brackets. The exact terminology is not completely consistent from source to source or season to season, but the practical takeaway is consistent: direct drops exist, bosses are the main target, and the odds are still low.
You may also see specific names such as Belial or Echo of Lilith mentioned in recent guides. Those references are useful as examples of the level of content involved, but they should not be treated as absolute proof that one boss is permanently the best Heir of Perdition source in every patch. If official seasonal notes do not clearly designate a top source, assume the safest boss strategy is the one you can clear quickly and repeatedly.

That final rule matters more than players sometimes admit. If moving up a tier doubles your kill time or causes frequent deaths, your real hourly chance of getting the helm may actually get worse. Torment I is the unlock threshold; it is not automatically the optimal farming tier, and the same goes for every tier above it.
You may also notice item power references that vary slightly by source, with Mythics often described as dropping around 800+ or 850 depending on the seasonal interface. That difference does not change the farming plan. What matters is that Heir of Perdition sits in the top item bracket and requires endgame progression.

They are worth treating as extras, not as your main plan.
Some recent public guides report Heir of Perdition as a possible outcome from Helltide chests. That is plausible enough to keep in mind, but it is less firmly corroborated than the Jeweler recipe or boss-based Mythic hunting. The practical use is simple: if you are already farming Helltide for other reasons, open the worthwhile chests. Just do not reroute your entire endgame around Helltide alone if the only thing you want is this helm.
Older and community-driven advice sometimes lists Obol gambling through the Purveyor of Curiosities, also called the Cabinet of Curiosities in some writeups. While a Mythic outcome may be technically possible in high-end difficulty states, it is a very poor targeted strategy for Heir of Perdition. You are rolling a huge pool, the item is extremely rare, and you are not meaningfully reducing randomness. Use Obols as bonus value, not as a dedicated Heir farm.

The biggest mistake is psychological rather than mechanical: treating direct drops as the “real” way to earn the item and crafting as a fallback. For Heir of Perdition, crafting should be your main plan from the start. A lucky drop is just the shortcut.
Usually yes, if your build wants a high-offense universal helm and your defensive basics are already stable. Heir of Perdition is strongest when your character can actually exploit the damage increase instead of using the slot to patch survivability problems. If you are still struggling to stay alive in Torment content, a more defensive helm can sometimes carry progression better until the rest of your gear catches up.
For most endgame-ready characters, though, this is the kind of Mythic you craft because it stays relevant across builds, seasons, and even class changes better than more niche items do.
