This is a Magus class feature.
Magus Orders are anything from a guild or organization, to a religious wing or order, to mercenary companies or minor groups of martial spellcasters. The Orders are unique, only sharing in the principle of weaving magic into combat seamlessly. Magus Orders, unlike guilds and orders dedicated to more serious spellcasting, usually prefer only a handful of magic schools, dedicating and focusing their attention on those.
- Choose a Magus Order from the list of orders.
- Your choice grants you features at 1st level and again at 8th, 12th, and 16th level. Those features include order spells.
Order Spells
- Each order has a list of associated spells. You gain access to these spells at the levels specified in the order description. Once you gain access to an order spell, you always have it prepared. Order spells don't count against the number of spells you can prepare each day.
