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

I created an alternative upgrade, and besides the effects, let's move on to the unimproved version.

People clearly like this unit too much - they suggest giving them vampirism and unholy word spells (these were different people suggesting it), I find it funny. I had similar urges to give a bunch of abilities to dwarves - I was so enthusiastic about magical golems that I gave them resistance, mana drain from the hero, and from units, and a channel from the archmage, and golem abilities like immunity to slow and infinite retaliation...
