How do you craft mind runes on RuneScape?

The same way you crafted Air Runes, the mind altar is located west of Ice Mountain near the edge of the Wilderness, and is east of the Goblin Village. You may unlock the music Miracle Dance here. The closest bank is in Edgeville, but that path crosses the Wilderness which should not become a problem if you travel along the Wilderness ditch. The second closest bank is in Falador.
