Diablo 4 Season 15, officially named Hell's Legacy, brings a landmark gameplay update that revives classic Diablo 2 mechanics for modern Diablo 4 gameplay. Beyond returning legacy encounters with Lesser and Prime Evils and classic unique items, the most anticipated hidden feature of this season is the full introduction of traditional runes and runeword crafting. Unannounced during the BlizzCon panel, this secret addition reshapes item building and build diversity entirely. This guide breaks down all new D4 Season 15 runes, rune upgrading rules, and Horadric Cube crafting recipes.
Diablo 4 Season 15 New Runes List, How to Get & Use
Diablo IV Season 15 adds 52 brand-new unique-tier runes, split into two functional categories: Ritual Runes and Invocation Runes. These two types work in a paired system for runeword crafting. Additionally, six runes (Jah, Vex, Ohm, Thul, Lum, Eom) already existed in Diablo 4 and are integrated into the new crafting recipes.
The core mechanic of the new rune system relies on an Offering resource loop: Ritual Runes generate Offering when their effects trigger, while Invocation Runes consume accumulated Offering to activate powerful bonus effects. Both rune types support overflow stacking or extended duration mechanics for flexible combat usage.
D4 Ritual Runes (Offering Generation Triggers)
Ritual Runes generate Offering stacks once their trigger requirements are fulfilled. Each rune has a fixed Offering gain value tied to its unique activation condition.

How to Get Runes in Diablo 4 Season 15?
Runes drop from endgame activities. Players can farm Nightmare Dungeons, the Undercity, and boss encounters to obtain rune drops.
The Jeweler NPC also provides a transmute recipe: combine three runes to craft one new random rune. This transmute system lets players convert duplicate or unwanted runes into different runes needed for their runeword builds.
How to Use Runes in D4 Season 15?
Runes can only be placed into sockets on weapons and armor pieces. Jewelry such as rings and amulets cannot accept runes; jewelry sockets are reserved exclusively for gems.
Runes are the core components for creating runewords. Build your runeword setup by socketing Ritual Runes and Invocation Runes into your socketed gear. Ritual Runes passively generate Offering stacks whenever their trigger conditions are met during combat. Once enough Offering is accumulated, Invocation Runes consume these stored stacks to activate their effects.
Strategic Offering management is critical. Most Invocation Runes support overflow mechanics, so generating more Offering than the minimum requirement will unlock extra bonuses, such as longer durations, increased damage, additional summoned units, or bigger AoE size. Each Invocation Rune has its own independent cooldown.
D4 Season 15 Rune Upgrading System (Horadric Cube Ladder)
Players can upgrade lower-tier runes into higher-tier variants via 14 hidden Horadric Cube recipes. This fixed upgrade ladder standardizes rune progression, eliminating randomness in rune advancement. The complete upgrade sequence is strictly linear:
Tir → Eth → Ith → Tal → Ral → Ort → Thul → Amn → Sol → Mal → Ist → Vex → Ohm → Lo → Ber → Jah
All upgrades are processed exclusively through the Horadric Cube, with no alternative crafting methods available for rune tier advancement.
D4 Season 15 Runeword Crafting Rules
Season 15 revives classic Diablo 2 runeword crafting logic, adapted fully for Diablo 4’s item system, with consistent rules across all 19 new runewords:
Base Item Requirement: All runewords require a white-quality base item of the specified equipment type. No magic, rare, or unique bases are valid for crafting.
Rune Combination Logic: Standard runewords use one Ritual Rune + one Invocation Rune in a two-socket base item (a system inherited from Season 6). Advanced runewords require 3–6 runes in fixed sequences.
Recipe Hiding Mechanic: The Horadric Cube recipe displays as "???" until the final required rune is placed into the cube.
Item Inheritance Rules: Finished runeword items retain the base item’s original item power. Scalable stats adjust based on item power, while fixed stats remain static.
Rune Sequence Accuracy: All rune orderings strictly follow the original Diablo 2 runeword formulas (e.g., Enigma requires Jah + Ith + Ber in identical order for both games).
