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

Wall of Swords => Wall of Thorns (for example) and now it's the ground.

As I understand it, immunity to earth magic doesn't grant immunity to the "slow" spell if it targets the ground – is this even possible to resolve?
For example, I took a simple approach: all creatures with immunity to earth (earth elementals and Earth & Air dragons) also received an ability that grants immunity to slow, but there are few individual abilities for specific spells, so this solution isn't really a solution...

I decided to continue working on the gnolls; the shaman can be made using the Academy mage model, the main thing is to create new legs for him.

Excellent! I think it will turn out interesting (especially the attack animation without a magical wand).

Could you make a Gnoll Shaman based on the Orc Shaman? Let it be a Gnoll Shamaness.

Could we make a Gnoll Shaman based on the Orc Shaman? Let it be a Gnoll Shamaness.

Changing gender after upgrading is quite strange.
And regarding priests/priestesses: I suggested making a lich on a mage for the Necropolis faction, and a priestess could be made on a succubus.

Are we talking about the 4th or 1st level of the Lizardfolk town right now?

I once suggested making gnoll shamans instead of lizard priests for the fourth faction.

Sorry, when will the new version be released?
