Banner Wall creates a wall of Arcane Energies, whilst it is active all incoming damage to people on the inside of the wall is reduced by 1d12.
After 12 hours you start building up Exhaustion, you gain a level of Exhaustion every two hours after this point. Every odd spell slot up the spell goes will make it take an extra hour to gain a level of Exhaustion, Every even spell slot up the spell goes will add an extra dice to the reduction.
The wall can only be used on visible land, if the caster can no longer see an area the spell will fail in that area. to redo the spell in that area it must be recast.
The spell can be broke through by finding the original material used to cast the spell and breaking it. Breaking the casters line of sight, a higher level dispel magic or counter spell.
The material has a AC equal to the level of spell slot used +7.
As a ritual it takes 2 hours to cast.
