In Diablo 4 Season 15, transmuting 2 Ber runes and 1 Grand Sapphire in the Horadric Cube produces 1 Jah rune. Both Ber runes are consumed, so reserve another Ber first if Enigma is your goal. When planning resources alongside D4 Gold, count the required runes and gems individually.

How to Convert Ber Into Jah

Place 2 Ber runes and 1 Grand Sapphire in the Horadric Cube, then transmute the combination. This is a hidden recipe, meaning its absence from the visible recipe list does not mean the combination is unavailable. Match the gem name exactly: this conversion calls for Grand Sapphire.

Check the two rune names and the gem quality before committing the materials. The result is one Jah, not a Jah plus a remaining Ber; the conversion spends both input runes.

Starting With Lo Runes

You can craft each Ber by combining 2 Lo runes and 1 Grand Topaz in the Horadric Cube. Lo is a specific rune name, not a description of any low-level rune, and a Royal Topaz does not meet the Grand Topaz requirement.

Calculated from these recipes, making one Jah entirely from Lo requires 4 Lo runes, 2 Grand Topazes, and 1 Grand Sapphire. First make two Ber runes, then use those two Ber runes in the Jah conversion. That total covers the Jah alone.

How Much Should You Save for Enigma

Enigma requires 1 Jah, 1 Ith, and 1 Ber together with a Normal white chest armor base in the Horadric Cube. The remaining Ber is a separate ingredient: creating Jah does not satisfy both rune requirements.

If you have no Jah and plan to make it from Ber, save three Ber runes in total. Two become Jah, while the third stays available for Enigma. Starting entirely from Lo, that works out to 6 Lo runes, 3 Grand Topazes, and 1 Grand Sapphire, with Ith and the chest armor still required separately. These totals are calculated from the two conversion recipes and Enigma's ingredients.

Count your stored Jah, Ber, and Lo runes before choosing your next step. Any decision to buy diablo 4 runes should follow that inventory check and your exact missing-material list. For an Enigma craft, set aside its separate Ber before loading the two conversion runes into the Cube.
