Hi back again
here's what I was thinking for desert wind

3rd level vestige
when bound gives proficency with all desert wind preferred weapons
when bound deal half damage with desert wind maneuvers to foes immune to fire
+5 to tumble checks
one 2nd level desert wind maneuver
one 3rd level desert wind maneuver
one 4th level desert wind maneuver each automatically recover after five rounds
2 desert wind stances of 2nd to 4th level
for the purposes of these maneuvers treat your Effect Binder Level as your Initaitor level.

this is the basic template I'm thinking of using what do you think?
