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

Is Magic Fist not too basic for level 6?

Mages were conceived as powerful support units; Magic Fist is a mandatory spell for Academy mages, so it shouldn't be removed. You could give a mage Magic Fist at the expert level; they would also get Fireball, in memory of the Archmage.
The mage won't be shooting.
