Diablo II: Complete Rune Upgrade Guide

Rune upgrading in Diablo II is the process of combining lower-tier runes into higher-tier ones using the Horadric Cube. It is one of the most important ways to obtain high runes (28# and above) in the endgame.

Below is the complete list of upgrade recipes, organized by rune tier. Note that not all runes can be upgraded directly, and starting from a certain tier, specific gems are required.


1. Basic Upgrade Rules

Rune Range Recipe Notes
#1 – #9 3 same runes → 1 rune one tier higher No gem required
#10 – #20 3 same runes + 1 specific gem → 1 rune one tier higher Requires a specific type of gem
#21 – #33 2 same runes + 1 specific gem → 1 rune one tier higher From #21 onward, only 2 runes are needed

2. Recipes #1 – #9 (No Gem Required)

This is the simplest tier. Just place 3 identical runes in the cube.

Input Output Input Output
3x El (#1) → Eld (#2) 3x Ith (#6) → Tal (#7)
3x Eld (#2) → Tir (#3) 3x Tal (#7) → Ral (#8)
3x Tir (#3) → Nef (#4) 3x Ral (#8) → Ort (#9)
3x Nef (#4) → Eth (#5) 3x Ort (#9) → Thul (#10)
3x Eth (#5) → Ith (#6)

3. Recipes #10 – #20 (Gem Required)

Starting from Thul (#10), each upgrade requires a specific gem in addition to the runes.

Input Required Gem Output
3x Thul (#10) + Chipped Topaz → Amn (#11)
3x Amn (#11) + Chipped Amethyst → Sol (#12)
3x Sol (#12) + Chipped Sapphire → Shael (#13)
3x Shael (#13) + Chipped Ruby → Dol (#14)
3x Dol (#14) + Chipped Emerald → Hel (#15)
3x Hel (#15) + Chipped Diamond → Io (#16)
3x Io (#16) + Flawed Topaz → Lum (#17)
3x Lum (#17) + Flawed Amethyst → Ko (#18)
3x Ko (#18) + Flawed Sapphire → Fal (#19)
3x Fal (#19) + Flawed Ruby → Lem (#20)
3x Lem (#20) + Flawed Emerald → Pul (#21)

4. Recipes #21 – #33 (Only 2 Runes Required)

From Pul (#21) onward, only 2 runes are needed per upgrade, but a gem is still required. This is the key to pushing toward the highest runes.

Input Required Gem Output
2x Pul (#21) + Flawed Diamond → Um (#22)
2x Um (#22) + Topaz → Mal (#23)
2x Mal (#23) + Amethyst → Ist (#24)
2x Ist (#24) + Sapphire → Gul (#25)
2x Gul (#25) + Ruby → Vex (#26)
2x Vex (#26) + Emerald → Ohm (#27)
2x Ohm (#27) + Diamond → Lo (#28)
2x Lo (#28) + Flawless Topaz → Sur (#29)
2x Sur (#29) + Flawless Amethyst → Ber (#30)
2x Ber (#30) + Flawless Sapphire → Jah (#31)
2x Jah (#31) + Flawless Ruby → Cham (#32)
2x Cham (#32) + Flawless Emerald → Zod (#33)

5. Tips & Important Notes

Hel (#15) Special Use

Hel (#15) is also used to unsocket items. The recipe is:
Hel (#15) + Scroll of Town Portal + Socketed Item → The inserted runes/gems are destroyed, but the base item remains.

Gem Quality Progression

Quality Notes
Chipped Lowest quality; drops abundantly in Hell difficulty
Flawed One tier above Chipped
Standard e.g., “Topaz” (no prefix)
Flawless e.g., “Flawless Topaz”

Gem quality increases as rune tiers go up. It’s a good idea to upgrade lower gems in advance using the cube.

Suggested Upgrade Strategy

  • For runes below Gul (#25), upgrading 3 → 1 is generally safe to save stash space.

  • Starting from Gul (#25), high runes are extremely rare and upgrading costs are significant (e.g., 2x Lo to make Sur). It’s often better to keep duplicates for runewords rather than upgrading immediately. For example, using 2x Lo to make Fortitude is usually more valuable than cubing them into a single Sur.

Resurrected vs. Classic

These upgrade recipes are identical in Diablo II: Resurrected and the original Classic version. All recipes also work in single‑player (offline) mode.
