Sorry if the formatting comes out poorly, my code is pretty sloppy.
Declare a set with the sash. You can call it whatever you wish, just be sure the above set matches the code in the function below...
Code
sets.YourAskSashSetname = {waist="Ask Sash"}
Code
function job_buff_change(buff, gain)
if buff == 'Boost' then
if gain then
equip(sets.YourAskSashSetname)
disable('waist')
else
enable('waist')
end
end
end
If you already have the same function to control your body for Impetus, you can nestle this part into that. Copy from "if buff ==" to "end" and paste that into the function you might already have.
Hope that works
