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

I changed the Blood Wrath bonuses; I'll adjust the unit stats soon.

And how did you manage to add other abilities through Blood Wrath that aren't already available to Orcs? I experimented with it myself and couldn't get it to work for abilities that were already defined in the default Orc abilities (like accuracy, permanent retaliation, etc.). I wanted to try adding immunities.
