FIRST:
you need to make sure your server can read drop rates of less than 1% (0.01% to be exact)
by going to NPCDrops.java and changing the 100's to 10000
and then open NPCHandler.java and find the MonsterDropItems void
and change the
Code:
double roll = Math.random() * 100;
to
Code:
double roll = Math.random() * 10000;
ALSO
i use corp beast as ID 3597 and real Runescape item ID's
Code:
