There are a huge variety of new Runes in WoW Classic Season of Discovery, and some classes share common unlock methods with others. All classes have at least one WoW SoD Rune locked behind both Grizzby's quest line and the new Waylaid Supplies rep, for example. But although Warriors and Warlocks both need to get a Soul Of The Sea to get a Rune, Warriors have a bit more work to do.
