Arcane Rune Wall is a background wall that is purchased from the Traveling Merchant for 250 each. It is one of the few animated walls, as the runes displayed change every few seconds.


  • The runes themselves do not spell anything and cannot be altered to control their "spelling".
  • The change of runes is synchronized across all placed Arcane Rune Walls in a world.
  • When placed in large patches, some tiles may not display a rune.
    • This also applies to single pieces of Arcane Rune Walls within patches of other wall types.
