Please make it so that the flight aspect of Windwalk and the Fly spell are not mutually exclusive, but overlap instead.

If neither are active, both work identical and have the same echo as normal.

If Fly is active, Windwalk CALL WINDWALK results in a normal echo, and still gives both effects (pathfinding and flight).

If Windwalk is active, C FLY activates and gives the echo:

You feel a little lighter. (First time)

You are already flying. (Second time you cast fly)

And Fly is added to the affects list as normal. So your affects list would look like this:

Affected by:
Power: 'windwalk' for 30 hours.
Power: 'windwalk' for 30 hours.
Spell: 'fly' for 15 hours.

The current setup can become very confusing trying to juggle fly and windwalk when going into cities or avoiding them, especially for shapeshifters.
