Heavy Armor (Ex)
At 13th level, a magus gains proficiency with heavy armor. A magus can cast magus spells while wearing heavy armor without incurring the normal arcane spell failure chance. Like any other arcane spellcaster, a magus using a shield incurs a chance of arcane spell failure if the spell in question has a somatic component.
