Jah is one of those runes that can change how a Diablo 4 build feels. Its Teleport effect replaces your usual evade, giving you a mobility option that brings back memories of Enigma from earlier games. If you're planning a Season 15 build around it, you'll need patience as well as a sensible farming route. There are plenty of D4 items worth collecting along the way, but Jah is the prize for players who want that extra freedom to move.
Make the Most of Undercity Runs
Kurast Undercity is a good place to focus your search. Before entering, use a Greater Tribute of Harmony to direct the completion rewards toward runes. Once you're inside, keep an eye on the timer and build attunement as you fight. Better attunement improves the reward at the end, so rushing straight through without paying attention to it can leave value behind. Try to learn where objectives appear and which enemy groups are worth stopping for. A quick run is useful, but a quick run with strong rewards is better. Even then, you're not guaranteed a Jah drop, so think of each clear as another chance rather than a promise.
Watch for the Portal Prankster
There's another reason not to charge blindly through the Undercity. The Portal Prankster can appear during a run, and it's worth chasing if you've got time to spare. Defeat this unusual treasure goblin and extra chests can appear near the exit after the boss goes down. Those chests offer more chances at useful loot, including runes you might need for crafting. Keep the clock in mind, though. If pursuing it puts the entire run at risk, finishing the dungeon may be the safer choice. You'll soon get a feel for when the detour is worth taking.
Put Spare Runes to Work
Didn't find Jah Take a look at what you've collected before starting another run. A Jeweler in a major hub such as Kyovashad or the Kurast Bazaar can combine three matching runes for a random rune of the same rarity, with a gold fee attached. Three Cem runes, for example, can be exchanged for another Legendary rune. The result isn't guaranteed to be Jah, so keep any runes your current builds still need. Mercenary caches are another useful source of materials. Spend time with your hired companions, raise their rapport, and check the vendor in the Mercenary Den for caches you can purchase with the appropriate currency.
Build a Farming Routine
A practical routine is simple: run the Undercity with a suitable tribute, collect every reward you can safely reach, then sort your spare runes at the Jeweler. Check mercenary caches between sessions rather than treating them as your main source. If you're also comparing D4 items buy options, remember that the rune is only one part of the build; the rest of your equipment still needs to support the way you play. Jah may take several attempts to turn up, but those extra runes and materials can make each session feel worthwhile.
