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

It's strange, but my magic schools remained the old ones; there are no water or fire spells, etc.

Looking at these units, it seems that 50 HP might be too little for them – it turns out to be roughly the same as liches. These trolls are so bulky that it looks like they should be able to tank and withstand attacks. Although their attack, defense, and damage are high for a Tier 5 unit.

Just my opinion – around 70 for the non-upgraded version and 80-90 for the upgraded/elite version would be ideal, with a slight reduction in attack, defense, and damage.

He's almost like a cyclops, with 200 HP! =)

They are so awesome!

I looked at the stats again and still felt a little sad - for tier 6, they are quite weak; even wyverns will be stronger, considering these birds have slightly less HP. Although, they don't really need much more HP, maybe increase it to 100 for the upgrades, and also increase their attack, defense, and damage.

I didn't touch the city buildings because I want the unit to be compatible with the current mod and the vanilla game, and there the buildings have different model values – so for now, I'm not touching the buildings.

 

A simple Rukh is weak; it should be cheap and easy to build, while the upgrades should be expensive.

 

Tier 4 remains; perhaps it's worth trying to make a Stone Lizard because Tier 1 and Tier 3 aren't particularly fast, and the lizard could have a speed of 5-7 points.

 

Alternatively, we could move the Mage to Tier 4 and make Tier 5.

 

We could also consider the Golem – make it a Numidian that not only attacks but also casts various spells.

 

This is just a recolored Phoenix of Zahar, with modified effects, and there's also a new effect for attacking a unit.

I suggest renaming:
Ruhi - Gamayuns
Snowy Eagles - Gveykhirs
Birds of Thunder - Birds of Storm

I don't see the point; people will have questions about who the Gamayuns are, they'll Google it, and it's a cringe-worthy, wingless, legless bird) + it doesn't sound as intimidating.

And Gveykhira also sounds cringe-worthy because of the similarity to Gwaihir, the king of eagles in Tolkien's works; it's like calling mages Gandalf.

Well, and thunderbirds/stormbirds are almost the same thing; of the two options, I would rather choose the one that refers to the "trio."

In reality, I'm only confused by the Rocs, because the birds are actually called Simurghs and were taken from Heroes 7. Rocs in myths should be the color of rock and indistinguishable from them. Arab sailors described them as flying mountains. Simurghs, on the other hand, were with the Persians and were considered astral beings, unlike Rocs.

Secondly, the essence is more important than the appearance: the Gamayun is a prophetic bird that conveys messages to the gods. Isn't that the purpose of a magical bird? Although I don't know the lore of your birds.

I found Gweihira in the Berserk card game. There, it was a giant reptilian bird.

Storm Birds because of a more accurate translation.

There is also the Anqa - a giant evil bird created by Allah.
