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

Undead devil with a scythe from the Reaper, small imp without wings but with a scavenger ability, undead orc, undead goblin with a poisoned blade, undead dragon with green eyes, weakening strike, and strike of sorrow, undead Rakshasa?

Sorry for such silly examples.
