Detect Magic: Wizards can detect the presence of magic simply by concentrating and looking at an object. In game terms, this costs an action and the wizard can move no faster than a slow walk while doing it, but it costs no MP. If a wizard touches an object that is magical or a person under the effect of a spell, the wizard automatically and instantly detects the magic without needing to concentrate or look for it. This detection only allows the wizard to sense the presence of magic, the wizard learns nothing about the effects or spells used unless they spend time trying to identify the magic.
Identify Magic: A wizard can discern the properties of a magical item by spending six hours in careful meditation with the object. This process allows the wizard to determine all of the magical properties of a single magic item, including how to activate those functions (if appropriate), how many uses of magic remain, and what sorts of spells were used in the item's construction. The wizard does not need to spend MP, nor do they need to be secluded; as long as the wizard is allowed to handle the item without interruption or distraction, it only takes time. A wizard can also identify magic on a creature that is under a spell, but most living things will not sit still to be examined for six hours without some form of restraint.
I like the idea of having a wizard that could specialize in a school of magic and not be required to lose access to certain divination spells which seem like general utility wizard abilities. Also, giving wizards special magic-related abilities that they can perform 'at will' means that I could potentially run a game where wizards start with no spells.
The reference to MP? I'm using Magic Points to cast arcane spells, which is an idea taken from the psionics system in Stars Without Number.
