Magic Techniques

Magic techniques are often used by non-magi. They are really spells, even if they don't resemble them.
A magical technique is a specialized form of magic, one which allows the user to internalize the flow of mana through their body and channel it in the form of a spell instinctively, granting them the benefits without having to use words or gestures.
Magical techniques aren't weaker than spells. In fact, they tend to be more efficient uses of mana, and far, far faster to use in combat. Some Illisyr magi in particular use them extensively, especially those without large mana reserves.
