Arcane Rune Wall

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