RTF is a global modification that replaces all towns in the game.

then it would be better to focus on magic rather than education, or consider this option: rework the icons and names of spells. For example, let's take the Mind Lord: "slow" is already a cast of the earth element, but the question is how to connect "confusion" to the earth element? The answer is to redesign and rename it so that it resembles the earth element, remembering Heroes 4 - there was a "swarm of bees" spell in nature magic that caused the target to skip a turn and did not affect mechanics, elementals, or undead. So, we rename "confusion" to "swarm of bees" and give it a "swarm of bees" animation, and we get a spell related to the earth element. However, there is one BUT: we already have a summoning spell called "swarm of bees," and the Hive also casts a swarm. So, in this case, we would have to change these two spells as well.
