Summoner (Unchained)

Weapon and Armor Proficiency

Summoners are proficient with all simple weapons and light armor. A summoner can cast summoner spells while wearing light armor without incurring the normal arcane spell failure chance. Like any other arcane spellcaster, a summoner wearing medium or heavy armor, or using a shield, incurs a chance of arcane spell failure if the spell in question has a somatic component. A summoner still incurs the normal arcane spell failure chance for arcane spells granted by other classes.
