'''Arcane Barrier''' surrounds its caster in an anti-magic barrier that grants them immunity to targeted low level offensive spells. 

The highest spell level nullified in this manner is based on the caster's [[Arcane Symbols]] (AS) or [[Magic Item Use]] (MIU) ranks, depending on the method of activation. The caster becomes immune to spells of:

{{equation box|{{math|Spell Level &le; 3 + ((Arcane Symbols or MIU Ranks) / 25)}}}}

For example, a caster with 50 Magic Item Use ranks rubbing a crystalline prism becomes immune to spells of level 5 and lower.
