I propose a race of reclusive hermits – the Forest Guardians! Once, humans staged a great uprising. They rebelled against their king and retreated into the forests (an unfinished Greenpeace!). Elves often sent spies to them and instilled their teachings (like a nature cult). The humans re-educated themselves and became overzealous Greenpeacers. In the forests, they met lizardmen and began building a new nation! A unique feature of these fanatics is their ability to use bushes and trees as cover and invisibility cloaks! They also have the ability to train certain neutral creatures into specific units of their city. The higher the skill, the greater the chance that these creatures will be trained at all; if they are unlucky, they will have to be killed (the neutral creatures). It is also possible to create extra slots for warriors, but this is debatable. Oh yes, during a siege, the castle has no walls, but instead has a lot of trees that serve as towers, but the warriors themselves are not visible in them. There are many trees, and from this comes the ability to re-hide from one to another, hallucinations that create the illusion that a warrior has emerged from a tree or moved to another, etc.
There will be lizardmen, snipers, and cunning gnolls (who can unnoticedly move from one tree to another. An attack by melee warriors from a tree (if the unit was not previously spotted) throws the enemy into shock, and they do not respond to the attack (and if a unique racial skill is developed, there is also a chance to stun these warriors for a turn)
1 lizard (no abilities) - lizard warrior (hiding in trees (in the future, this skill will be called camouflage))
2 gnoll (camouflage) - cunning gnoll (unnoticed movement between trees and camouflage)
3 nature guardian (human) (casts spells (the simplest)) - guardian fanatic (mage, grows a tree (once per battle))
4 snake (flying) - poisonous snake (flying, weakening)
Guardian archer (human) (camouflage) - sniper (camouflage, full damage at range,
In melee, stuns the enemy if he jumps out from behind the trees with a 100% probability)
I will continue the list later
