I think the script should active for every minute 14 ? Whisper by GM Level 90 and above to activate it.
OnWhisperGlobal:
if( getgmlevel() < 90 ) end;
OnMinute14:
if( .Invasion ) end;
set .Invasion,1;
set .SelectedMap$,.Maps$[ rand( getarraysize(.Maps$) ) ];
switch( rand(4) ){
default: end;
// MAX : ~64 Different Monster in each Cases( 1 BOSS + 63 Normal )
// Case <X>: Invasion( <BOSS>,<Amount>,<MOBID>,<AMOUNT>,....,<MOBID>,<AMOUNT> ); break;
Case 0: Invasion( 1815,300 ); break;
Case 1: Invasion( 1815,400 ); break;
Case 2: Invasion( 1815,350 ); break;
Case 3: Invasion( 1815,450 ); break;
}
initnpctimer;
end;
