ok, you know the config where you have all your configs like Belt manager and satsher? you also edit like merc options... well theres a section in that config where it has the list of attacks;
Example:
Blizzard(#)
//Ice Blast(#) <-------- This ring a bell?
//Glacial Spike(#)
(on this example your are using Blizzard as your
only attack and you removed the other two)
It's simple just remove the // to use that attack or add // so you wont use that attack. This is off the top of my head but more or less thats how the script looks im not home so I cant copy paste but this should help ya...
