How long does light shrink magic last?
First of all, this shrinking magic is not permanent, and its effective time is only 10 minute. In other words, after using magic, the magic will be invalid and restored to its original state after ten minutes.
Because the shrinking magic effect is too obvious, it is naturally impossible to set it as permanent magic, otherwise it will be too cheap to be short. If you use 10 candle, you can get three chances to become shorter permanently.
The magic in the magic shop is either one-off or limited. The valid time is 5 minutes or 10 minutes. Only the telescopic potion with the price of 10 candle can take effect permanently.
