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

so that, for example, a conditional smoke/fire takes the shape of a hammer around the hand?

No, I take effects from Heroes, for example, the effects of the Ifrit are taken from the magic shield spell (ring of fire), from the human hero (wave of fire), from the Inferno Grail (fireball in hand), etc.

The hammer needs to be assembled from different effects because there is nothing suitable.
