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

A tithe is a tax, dragons love gold, and they will be expensive, and will be on Tier 7.

I'm hearing for the first time that Keagan's betrayal works both ways, and also affects any unit... I think I removed this special ability from the cultists, but I need to check.

damn, I didn't test Keagan, but I checked a similar hero who changes the ability's effect - Elaine... she doubles the tax from peasants in her army... berserkers also pay double tax.

Some heroes in the game have a special ability. They are not tied to a specific Tier unit, even if they are originally designed for it. Sometimes this adds flexibility to the modifications. For example, Ligovsky's "Lizard Breeder" and Axel from the Order are not special abilities for a unit; they are special abilities for the ability itself (Sorgal's lizard bite and Axel's R. dash). Their special ability will work for any unit that has that ability. In Elaine's case, the situation is similar, in that she has a special ability for a Tier 1 unit, and a special ability for the "taxpayer" ability is added, and of course, she simply doubles the effect of the ability itself, regardless of who owns it.

About the Dragon taxes, the idea is interesting. It turns out your Orcs will be "walking under the Dragons." It's interesting what the storyline explanation for this will be and how the Orcs themselves feel about it... 🤔
*We're waiting for the Dragons themselves. Have you already decided what they will be based on?

Thinking about your idea with Betrayal, I came up with another way to implement the mechanic, but purely as an addition to Keagan's special ability. Initially, you need to set the betrayal percentage to zero, and adjust the description and name. Now this ability will simply be part of the hero's special ability. Since it won't work in normal situations, but it will work when "Keagan" is against them. Thus, this "new hero's" skill will give him weekly reinforcements proportional to his level, and in addition, it will allow him to recruit defeated Orcs in battle (this can be implemented with the hero's Honor/Reputation or something else that is more appropriate), the higher the hero's level, the higher the percentage at which units will switch to his side. 🤔

*This is just an idea, if you are going to implement similar mechanics.
