A Cham rune is a high rune which can be socketed into equipment in Diablo II: Lord of Destruction. The few rune words using Cham are not particularly popular, but Cham runes remain valuable for their Cannot Be Frozen property, and for their rarity as a rune, second only to Zod.
|Weapon||Freeze Target +3|
|Body armor or helm||Cannot Be Frozen|
|Shield||Cannot Be Frozen|
Socketing an item with a Cham rune increases the item's level requirement to 67, unless it was already higher.
A Cham rune is one of only a handful of sources of the Cannot Be Frozen attribute, important for protecting heroes reliant on attack speed from being chilled. Socketing a Cham rune in a helm, shield or armor can free up an equipment slot normally dedicated to getting Cannot Be Frozen, such as a ring slot for Raven Frost, for a more offensive option.
The Act 4 (H) Good treasure class has a chance to drop a Cham rune, as does the Act 5 (H) Good treasure class.
Cham runes are used in three rune words.
- Doom 'HelOhmUmLoCham' axe, polearm or hammer
- Hand of Justice 'SurChamAmnLo' weapon
- Pride 'ChamSurIoLo' polearm (ladder only)
Cham runes are used in one Horadric Cube recipe.
- Transmute two Cham runes and a flawless emerald to create one Zod rune. (single-player, open or ladder only)
