I haven't been able to find anyone addressing this idea so I thought I'd make a post to ask how I should handle some spell ideas I had.
The first was a blast of kinetic energy designed to throw a target through the air. how many shifts would this take and how could you deal with damage if you threw the target into a wall.
If you're going for distance, that's a manoeuvre. You tag the aspect for effect to move them to a different zone. If you're looking for damage, that's what the spell normally does. In this case, the damage comes from the impact rather than from the kinetic force itself.
Another idea I had involved combining water and fire evocation to fill a zone with burning steam, by using water evocation to fill the zone with mist and fire evocation to super-heat it. Would this be allowed in most games?
Again, sounds like a manoeuvre. Use whichever evocation makes the most sense. If you're in a damp location, fire makes sense since there's already moisture to superheat into steam. If you're in a desert-type environment, than use water since it's already hot enough.
Or, use both! In two consecutive exchanges start with the water evocation to douse the area with moisture, and the second to fill the area with mist. This way, you have two aspects to tag:
moisture rich and
filled with steam.
Just my [-2].
