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

A gnoll shaman... interesting idea! However, who will be on the 1st level of the town then? I don't want to put more gnolls there because, in theory, they will be casters, and we need to avoid synchronous plagiarism... any ideas? (besides frog-people! :D)

Still, 2 gnolls against 2 lizards... okay, let's see. We can always change it later. The idea of a gnoll in a hood is really good :D

Another head for the lizard warrior would also be useful, but whose?

Something like this, roughly knee-high.

We could also take icons from the Poles, and we had some good icons ourselves; we also need to create a Gnoll hero.

Forgot to ask how exactly to make the legs. Here's an example from the standing animation.

I didn't specify... The legs needed to be different models, a model for the left leg and a model for the right leg, but if each leg is colored with a separate texture, then everything is fine.
P.S.: I also found an interesting converter from the Heroes format to the obj format; it might also convert it back.

Okay, let's continue with the clarifications. The foot should be positioned at zero, but which axis should it be rotated along?
Regarding the converter, could you provide some guidance? I tried one, but it didn't work.

And could we create snake creatures based on the phoenix (but smaller) and make several of them, like ghosts (so that one unit is a swarm of snakes)? Accordingly, one of their abilities would be a chance to avoid physical damage.

Maybe they could add trolls to the lizardmen faction, who would be either infantry or casters.
