The level of the stored spell. Third, the frequency of use.
If the material level is higher, the maintenance time will be slightly longer.
However, this is only relatively speaking, the most important thing depends on the level of the stored spells.
If it is a trick stage, the higher the level, the shorter the reserve time.
For the level of the spell, it basically only takes a few days. Even if you don't use it, it will consume itself.
Also, if the frequency of use is too high, it will be consumed quickly. Of course, this is only limited to the case of storing one magic. If you reserve magic, it can basically be said to be a one-time consumable.
All in all, this is a very expensive magic energy array that has many more restrictions than constant spells. Compared with other alchemists, it is also relatively useless.
However, as there is currently no other way, we can only make do with it temporarily.
