[Research] Droprates

[pro4never]

Ok well I've been messing around with drop rates trying to get them as good as possible. What I am doing currently to test them is I added a new drop rule (cq_dropitemrule) and changed it so 3 different monsters all used that monster class.


Currently for these tests I will be using cg_dropitemrule chance of 100,000,000. All statistics are drop_item_chance in cq_monstertype

I am not sure if it makes much of a difference but I have explode_item_chance1 10 explode_item_chance2 30 explode_item_chance 3 60 for all 3 monsters, I believe that has something to do with how many items it drops but I am not sure yet, if anyone knows or I find out I will update this posts.


The tests


The tests I did so far are very basic, change the drop_item_chance field to something, change next monster to a product of that and same for 3rd monster, then load the server and check the drop rates. NOTE YOU NEED TO RESTART SERVER FOR DROPRATES TO UPDATE (if there is a gm command to reload droprate/monstertype table please let me know, it would help)


First round of tests

drop_item_chance 10,000 - 100 monsters dropped 8-12 items over 300-400 monsters
drop_item_chance 20,000 - 100 monsters dropped 18-24 items over ~200 monsters
drop_item_chance 30,000 - 100 monsters dropped ~ 30 items over ~100-200 monsters

So, in this case a drop item chance of 10,000 meant aprox 1 in 10 monsters dropped something. Idealy it should be somewhat lower in my oppinion so I moved on to a second set of tests.


Second Round Of Tests


drop_item_chance 5,000 - 100 monsters dropped 5 items almost exactly over 300 monsters killed, next 100 dropped around 10-12 though... one of the monsters appears to have droped about 4 items though...
drop_item_chance 10,000 - 100 monsters dropped ~ 10 items again over 200 kills, confirmed first test
drop_item_chance 15,000 - 100 monsters droped ~ 16-19 items over 400 kills

I used 10,000 in the first test but I just wanted to confirm to myself that it was accurate in this one as well (to confirm the original results)





Conclusion

This is simply a guide for people who are trying to configure their drop rate settings to understand somewhat how they work and what is a good setting. I still havnt found the "perfect" drop rate but, using a dropitemrule chance of 100,000,000 somewhere in the low thousands sounds about right

review
all rates @ 100,000,000 chance in dropitemrule

10,000 ~ 1 item per 10 mobs
20,000 ~ 1 item per 4-5 mobs
30,000 ~ 1 item per 2-3 mobs
5,000 ~ 1 item per 15-20 mobs

If anyone wants to come test out some things with me on my server send me a pm, server is up most of the time currently being used for exp/droprates and some translation work.

Thx,
Its looking good, Ill try it out as soon as Ive Finished trans on cronus/market npcs

set all dropitemrule to 100 mill in chance
then set drop_item_chance to 1500 and drop_money_chance to 5000 in cq_monstertype and u should have a good balance for a f2p server

also tweak the min and max golddrop

i set all mine to min 200 and max 20000

I know how to do all that, i was just doing tests on what various values will give people so that if they want a certian monster to drop lets say 1 item every ~10 kills they dont have to test a ton of values to get it.

can u tell me how to do with the easy way?

There is no easy way... its alot of work to fix all the droprates. The closest thing to being lazy is edit them for one monster and then copy that onto all other monsters and then only edit a few of the items... but then you wont have a very good variety of drops

[nooneatall]

make one rule for each map..
then make one rule for each boss on each map
then one rule for....... and so on..

if you want to change the already included drops to be more or less do this in your mysql console:

use my
update cq_monstertype set drop_item_change='value':
update cq_monstertype set drop_money_chance='value';
