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

the main monsters are only from the Fortress.

I misspoke, not the main ones, but the elite ones.

When I was calculating the stats for the Riders, I encountered a problem: when calculating the stats for level 5 creatures, the increase is always 3, even though the monsters should have different increases. I think the increase for them can be increased by 1.
