[@Lucky] Ah that is fine. To answer the question, magic is 'active' once cast and things such as wards will last for a period of time. The length of time a Ward stays on for is dependent on how much Aether is put into the spell and the kind of Ward it is. For an effect to stay on a piece of equipment for an extended period of time, the caster would have to balance the drain on their reserves with the cost of the effect. This isn't typically something that is easily done, however, so it may take some time to learn if you wish to do it.
