Wind of Change

Therefore, these issues need to be fixed, not made easier to obtain.

I would like to hear your ideas for fixes, if possible. Because, in my opinion, there aren't many ways to do it: 1. Limit the number of uses per day; 2. Increase the required amount of mana for use. In the first case, some spells may become useless. For example, Dimension Door once a day for XL+U is not such a huge advantage that the entire game should be built around obtaining this spell. Again, the value of logistics, stables, etc., will increase, because the goals of Dimension Door are simple: saving mana and reaching areas inaccessible on foot. The same Teleport with two or three uses a day only makes it necessary to increase the number of support units (although, for one use a day, the spell is practically useless; you will even have to split up heroes after obtaining it, and for two or three uses, nothing will change much, because approximately that many times Teleport is used during the day). Increasing the required amount of mana does not seem like a serious fix, as it again only increases the value of skills such as intelligence, for example, and also hats. And in the game, it will be standard: one player will find all this useful, and another will not. In this context, balancing the schools of magic looks promising (maybe we will see Dimension Door in water someday? :o)
