Orcish Rune

The Orcish Runes are runes in the orcish language that were written by Gul'dan as he journeyed into the Tomb of Sargeras during the Second War. Following the Third War, the night elf Maiev Shadowsong found them and was able to read them.

The Tomb of Sargeras raid is peppered with these clickable runes that reset each week with every lockout. Only one player can click each rune. Upon clicking one, the rune transforms you into Gul'dan and lets you try to take down your allies. You can swipe at them with a scythe, you can hurl fireballs, and you can fire out a concentrated blast of heat, all variants of his abilities from the fight in the Nighthold.
