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

I was checking out the new Necropolis creatures, and they don't have any ranged attackers. They should replace the 3rd, 4th, and 6th-level creatures; two of them could be made ranged attackers. In principle, the 4th level could even remain the same, but just be made a ranged attacker.
By the way, what's planned for the Renegades?
