You can remove CS from Kecoon Fighter...lol
The IDs of Kecoon Fighter are 102 and 152. To make sure their drop doesn't code for another monster, put this into a query and hit execute:
Code:
update k_monster set sItem='102' where sSid='102'
update k_monster set sItem='152' where sSid='152'
Then, go find it via K_Monster_Item.
Code:
select * from k_monster_item where sIndex='102' or '152'
You'll find their rows, then just make it into update codes.
For example, if the Chitin Shield ID is on iItem03:
Code:
update k_monster_item set iItem03='0' where sIndex='102' or '152'
Either that, or you can just go fish for both IDs in k_monster_item if you don't wanna deal with update queries.
