(PROBLEM) Drop Size?

I have added Bone roc and added him to drop many things, items, inmortals, astrals, silver coins, gold coins, special scrolls, etc, but when i kill him it drops only 21 coins and some tablets... not even gold, he was droping gold before i added custom drops..., i want to he drops like original roc, that drops big size of drops. What i need to modify that? Its easy?

duplicate Roc's rebojcommon & refobjchar rows and change id, codename128 ofc, then replace the roc's .bsr file to death roc's. idk if death roc uses the same skills as roc, if doesnt it may cause crash, but since their skeleton is the same i guess wont be any problems

Modify your unique lvl from objchar to max server lvl like if cap 120 then make roc lvl 120 and try to kill it again
