How to get the new Runes in Diablo Immortal?

Runes can appear as a rare drop through killing regular enemies, but it is said they are most abundant within the Abyssal Verge and the hellish castle of Erebban. Any wanderer seeking to master their items should seek out these deadly challenges for a chance at earning potent power.

Runes can drop from any activity where gold and items can drop, including overworld farming, dungeons, Elder Rifts and Raid the Vault. Runes may drop as bound or unbound. Each rune increases the basic attribute of the equipped item. Runes can only be embedded into specific gear slots depending on the rune.

A few Runes can be combined to increase the level of that Rune, but they must be the same type and level to be combined.
Enhance your Legendary items by adding affixes to them with Runes, amounting to incredible combinations and possibilities.
