Easy, the best example is the Horong Card!. Look at the Script:
4103,Horong_Card,Horong Card,6,20,,10,,,,,,,,136,,,,,{ skill "MG_SIGHT",1; },{},{ sc_end SC_SIGHT; }
So... your script should be like this:
5230,White_Drooping_Kitty,Gray Drooping Cat,5,250000,,500,,1,,4,0xFFFFFFFE,7,2,256,,0,1,274,{ skill "LK_CONCENTRATION",5; },{},{ sc_end SC_CONCENTRATION; }
Good Luck!
