Working on MotP templates:
"An air Element creature has a fly speed of 100
unless the base creature has a higher fly speed, with perfect
I can do BONUS:MOVE|TYPE=Fly|.IF.MOVEBASE.LT.100.THEN.100-MOVEBASE.ELSE.0
Not sure if that will work, but it won't override a
higher move speed. However, that won't work for creatures that don't have
Fly. That would be MOVE:Fly,100. Except that seems to set the
MOVEBASE to 100, overriding a higher Fly speed creature's speed...
