Temporal Link

When you cast this spell, you create a link between now and an older version of yourself through time and space for the purpose of channeling a spell that can be used later. The spell you channel must be of a lower spell level than the Temporal Link's level or the link collapses. After casting the Temporal Link you must cast the spell you wish to channel, the casting time is normal but if the spell requires concentration you must concentrate on that spell for the length of time you wish the spell to be active. Once you have finished casting the channeled spell the link automatically closes. You can only have one spell stored in the Temporal Link at a time because the next time you cast it the channeled spell is released.

At a future moment you may cast the Temporal Link spell again as an action (you do not need to cast this Temporal Link at a higher level, as you are simply releasing the previously channeled spell). Immediately, as if you had cast it yourself, the channeled spell will activate. If the spell requires concentration you do not need to concentrate on it because you already have (in the past).

At Higher Levels. You will need to cast the Temporal Link spell at one level higher than the channeled spell.
