Creating such specializations requires scripts, and they won't work in multiplayer. Do you have any experience working with scripts?
P.S. A specialization that provides a bonus to attack, for example, is also done with scripts, but they work in multiplayer.
Actually, I'm a beginner in this. All my work with scripts so far has been limited to self-teaching on simple things, like region-quests, hut-quests with conditions and rewards. That's all I've done so far. By the way, how do you make a 128*128*32 photo of your friends for Heroes?:)...
