Well it works for 3 classes for me..
load this ct and look for the ones that always work, i suggest you change their color to green and if you see a bad one change the color to red.
Run a few castles and restart the game do that 2-3 times to be sure.
Restarting your pc helps too
P.S. You just need to enter a castle to see if they work or not, if they are bad they usually have a weird address or values show up as "??"(also you can freeze the address and use a skill to be 100% sure). When you find a working one just delete the old skill pointer and drag a new one on "normal attack" pointer
