Hope i was right here ^^
For Example you wan to make another Poring.
Original Poring Database :
1002,PORING,Poring,Poring,1,50,0,2,1,1,7,10,0,5,1,1,1,0,6,30,10,12,1,3,21,0x83,400,1872,672,480,0,0,0,0,0,0,0,0,909,7000,1202,100,938,400,512,1000,713,1500,512,150,619,20,0,0,0,0,4001,1
Duplicated Database for New Poring :
( I used 25000 as example for the ID )
25000,PORING,Poring,Poring,1,50,0,2,1,1,7,10,0,5,1,1,1,0,6,30,10,12,1,3,21,0x83,400,1872,672,480,0,0,0,0,0,0,0,0,909,7000,1202,100,938,400,512,1000,713,1500,512,150,619,20,0,0,0,0,4001,1
Okay, now go to your
db/mob_avail.txt
add this
25000,1002
with this..your Monster with ID of 25000 will using the Poring Sprite ID ( 1002 )
