The look of the Wall Rune resembles some strong barrier which grants safety to the person it is attached to. It has its first appearance hidden in a treasure of Lordlake during the Sun Rune War. Decades later the Sun Kings in the Cave of the Wind, known for their strong ironcladed physical defense carried these crystals rarely. Only now during the Second Firebringer War the Wall Rune has become more popular among fighters and thus is sold in Brass Castle and Duck Village. Tricked by his mentor, young Rody carriers a Wall Rune which makes him unable to train his magic skills at all.
This rune provides double the defense for physical attacks, yet it makes you unable to move. Unless you just want to grant safe passage for a person that cannot do anything but defend, think about useful combinations with other runes. The Firefly Rune is qualified to attract enemies towards a well build defender. And the Knight Rune lets you prevent dying comrades from taking any more damage without kicking the bucket yourself. Or bring a Fortune Rune along to grind experience for little vulnerability. - Celes
