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

It’s impossible to add new spells to the game or create duplicates, but there are three spells that could potentially be reworked:
1) Hellfire Wave of the Overlord (fire element)
2) Diabolic Chain of Biara (air element)
3) Uber Meteor Shower (earth element) – it seems no one in the game has actually used this one (unlike the first two).

In addition, there are various prayers, banishments, and battle cries. There are also unit abilities (as I mentioned above) – in short, we need to try to incorporate these into the magic schools or at least link them to perks.
