drop rates

[Lanfir]

If your database (graciafinal.com) don't lie, the drop rate of wind stone from desert scorpion is ~30%
But after kill 50+ monsters there are no one wind stone hasn't been dropped.
I think you must check it.



I forgot about 1 very important thing.
We drop a lot of Ancient Tome of the Demon, which drop chance is more less.

They must check base

[Lanfir]

They must check base

no they must check drop rates, cause l2wh.com and l2on.ru show same drop chances

Its good... no1 will have 150 fast

I believe this is because the server's drops are edited...

This will be kinda hard to explain... bear with me through some bad english:

I believe all mobs ingame (or at least several of them) are edited in a way that they only drop, for each death, one of each of the following categories:

- Adena;
- Basic material;
- Key material;
- Others (possibly);

Remember your experience in this server: have you ever seen a single mob dropping anything over 3 items (excluding herbs, of course)? I have, in those rare cases:

- when it drops lifestones;
- when it drops a common or full item;

I can't remember any other occasion when it happened.

Have you ever tried dropping forgotten scrolls in dark omens/catacomb of the witch/silent valley? Don't you find it weird that ONE scroll always drops, but NEVER more than one? This was true 100% of the time for me, and although i only killed 20 or so mobs before leaving these places forever, it was marked in my memory, for being so weird.

In the example of the desert scorpions. Have you dropped a lot of silver nuggets?

Let's take a look at the scorpions' droptable:

http://www.graciafinal.com/?id=desert+scorpion#db.monster.main.22335#

There, you can see he can drop some basic mats: silver nugget, thread, metallic fiber, mithril ore, and enria. But, the chance for a silver nugget drop is 1/7, which, in our x30 rate, means it will always drop; If my theory is right, that means that other basic mats will never drop (since they come after silver nugget in the droptable). Confirm?

In that case, if the wind stones are considered by the game, for whatever reason, "basic mats"... You will never be able to drop them.

An alternative is tha tthey are considered "key materials"; in this case, their chance to drop would be...

Chance to drop nm robe keymats (comes before other key mats in droplist): ~37,04%; therefore, chance to not drop it = 62,96%;

Chance to drop mj robe keymats, if nm robe keymats DON'T DROP: ~37,04%;

Therefore, chance for nm robe keymats not dropping AND mj robe keymats dropping: ~62,96%*37,04%=23,32%; you see how smaller it is in relation to the nm robe keymats chance, for the single fact it comes after them in the droplist!

Finally, the chance for NOT dropping nm robe keymats, NOT dropping mj robe keymats, and DROPPING wind stones is very lower than what would be expected: only 13,07%, approximately one stone for every 8 kills.

The fact you killed about 50 of them MAY mean wind stones are considered "keymats" and you're just a bit unlucky, MAY mean wind stones are considered "basic mats" and you'll never see the color of them on this mob, or it MAY mean my theory is completely wrong altogether and that's just some really, REALLY bad luck of your part.

Anyway, this was (statistically) confirmed in MoS, Varka silenos barracks, and catacomb of dark omens. I don't know if other places suffer from the same problem.

Cheers!

omg its ctrl+c ctrl+v or this guy just have a lot of time?

[Lanfir]

I think he is little crazy if he write it himself. But his post may be has a lot of truth.

Waiting for admins comment

Im sure, its rly true (part about types of drops, i didnt read farer), cos i remember that the same info from admins, published long time ago.

I actually typed it...

Sorry for the confusing words... English is not my primary language. But I believe what I said is right, please ask for clarification if it is too uncomprehensible... ^^''

Cheers!

UP, same question

[Reckless]

it may be true; even if a droptable of a certain mob has several items that have a quite high chance of dropping, you will still get 2 or 3 things + adena, further reducing your chances of getting something positioned lower on that list

[Iblis]

so the drop table is a bit fucked up by the rates well what can u do. kill more mobs

sry for OFT
but i cant send pm :/ he wanna veryfication by image but dont show image

[petrajs]

maelstorm is right, drop rate in npcdata is made like in groups (categories) for example adenas / mats / keys / fulldrops....but its made for 1x rate, so when its 30x rate, drops are fucked up

droptable in npc data is like :

( item A 30%, item B 30%, item C 30%, item D 30%......)

so, items A B C will drop correctly, but item D will never drop because its already over the 100%, i dont know why, but that it is

we solved this on other 15x server by making script to divide and make new groups in npcdata, where the chance never reach 100% and it works properly

so for example concretly in this case, making the seperate new group only for wind stones, with chance +- 30%, can be a solution

Would be beyond awesome if this was implemented.
