Owh...my idea was doing it like this...
let take Lord Knight Card as example...
Original Script....
4357,B_Seyren_Card,Lord Knight Card,6,20,,10,,,,,,,,769,,,,,{ skill "LK_BERSERK",1; bonus bMaxHPrate,-50; },{},{}
When users try to restrict Lord Knight Card .. cant use combo with... MasterSmith Card ....
Original Script....
4361,B_Harword_Card,MasterSmith Card,6,20,,10,,,,,,,,2,,,,,{ bonus bBreakWeaponRate,1000; bonus bBreakArmorRate,700; },{},{}
so, Lord Knight Card script will be changed..and edit to this..
Edited Script :
4357,B_Seyren_Card,Lord Knight Card,6,20,,10,,,,,,,,769,,,,,{ if( isequippedcnt(4357,4361) < 2 ){ skill "LK_BERSERK",1; bonus bMaxHPrate,-50; } },{},{}
so the Lord Knight Card will have effect as long as its not equipped with MasterSmith Card together.....
it's just like this...
if( isequippedcnt(4001) <= 2 ){ Original Script Effect }
