Heroes 5.5 WarGame Edition - Tactical Edition.

Checked – it works!!! The idea: we use SkillPrerequisites, specifying a racial skill in it – this creates a connection between different schools in the mechanics (which we don't want), but in reality, it won't affect us in any way, since the racial skill listed in SkillPrerequisites is always available from the beginning of the game. Pros: - We solved the problem without actually creating a connection between different schools. Cons: - It is visually displayed like this (see screenshot), i.e., for each race, when viewing information about "mutable mana," their racial skill will be displayed instead of luck; in the case of "luck" itself, mutable mana is not displayed in the list of available perks, although it is available (the skill level embedded in the mod and displayed in the game will correct the situation).
