Magic Wall Rune

Creates a magic wall which lasts for 16 to 24 seconds and blocks one square meter. The wall will block all types of ammunition, spells and runes thrown or cast by both players and creatures.

Used heavily in PvP to trap enemies as well as to prevent projectiles from being fired at a given character. On Optional PvP worlds, it's used to block the attack from creatures but also to prevent them from walking over a certain tile and thus creating barricades or safe passages through them, since on these worlds they can be destroyed by walking over them.

For the spell, see Magic Wall.

In a previous update they were reduced from 4 charges to 3.

With the Update 10.00 the duration of the Magic Wall was changed from fixed 20 seconds to a random duration to make it more difficult to create "permanent" blockades.^[1] On Optional PvP Worlds, since the 10.01 Update, they get destroyed if a player walks over them.
