Weapon and Armor Proficiency

A skald is proficient with all simple and martial weapons, light and medium armor, and shields (except tower shields). A skald can cast skald spells while wearing light or medium armor and even using a shield without incurring the normal arcane spell failure chance. This does not affect the arcane spell failure chance for arcane spells received from other classes. Like other arcane spellcasters, a skald wearing heavy armor incurs a chance of arcane spell failure if the spell in question has somatic components.
