Lets start here
Explanation
drop chance of items you neeed to change in cq_drop_itemrule there is a column name chance then you can edit there by make 100000 or 100000 so the item will drop mostly and if you wish to change the type of item just edit at drop item 1= put your id items what you want and also at another column drop item 2,3,4,5,6,7 depends on you..
**Guides
each monster has a drop item rule type this can the be connected to the type field in the drop_item_rule table. So make new types and assign the relevant monsters to the new type.
you also can make it easy, go to your cq_monstertype and each monster in that map you give 1 unique dropitemrule ID
monsters in another map, another unique ID
than you can just add like 8 rows or something in your cq_drop_item_rule and you have of each map unique drops.
and than you do not need to change every row.
***
some added info
1. you will need your cq_monstertype and cq_dropitemrule.
2. E.G. cronus contains only madbulls,GreenDiants and bullywangs, lok for them in cq_monstertype.
3. look at the ids of the monsters and copy madbulls id, then go to cq_dropitemrule.
4. then look for your monstertype id in cq_dropitemrule in column, group_id.
5. in cq_dropitemrule you will see columns item0 - item14, chnage the numbers in those columns for the group id, those numbers are the items that monsters drop.
***
Using Query will be like this
update FIleName(Likecq_drop_item_rule) set <Here The column name>=Here Numbers or letters;
Drop rates
update cq_dropitemrule set item0=ITEM ID HERE;
update cq_dropitemrule set item1=ITEM ID HERE;
update cq_dropitemrule set item2=ITEM ID HERE;
update cq_dropitemrule set item3=ITEM ID HERE;
update cq_dropitemrule set item4=ITEM ID HERE;
update cq_dropitemrule set item5=ITEM ID HERE;
update cq_dropitemrule set item6=ITEM ID HERE;
update cq_dropitemrule set item7=ITEM ID HERE;
update cq_dropitemrule set item8=ITEM ID HERE;
update cq_dropitemrule set item9=ITEM ID HERE;
update cq_dropitemrule set item10=ITEM ID HERE;
update cq_dropitemrule set item11=ITEM ID HERE;
update cq_dropitemrule set item12=ITEM ID HERE;
update cq_dropitemrule set item13=ITEM ID HERE;
update cq_dropitemrule set chance=chance*10;
I believed this can help you but not sure if i am fullfill what you asking for..
Hopefully this can give you some idea
But as can seen in your cq_action you tick in the box so i guess to change the items you need edit the item id where is
