[DropPerKill] Drop rate system- DPK- Explained [Updated]2

There are a lot of brandishes and not a lot of players, so I would be shocked if it were accurate.

Most of these match my own experiences, though. Also, hilarious that Aston Staff is literally unobtainable because you can’t actually kill 7,000 Confined Firents between maintenances even if you play 24/7 without sleep. That one I completely believe is accurate.

Im not sure if dpk is real or just complete rng… found 2 arde daggers in 3 runs with my cleric. Regarding items, recipes and eq… i can say it’s rng. Got a botter in rukas plateau. Trying to hunt vine greaves and got it in 31 kills. Not sure if he (bot) got some or not lol.

One thing about ICBT was that the kill count of channels werent reseted. It happened on Itos after 2 months after release to “fix” memory leak of servers.

These values are how they were during iCBT.

I can absolutely confirm yellow gems and storm staffs on medakia dropping roughly every 100 kills for example. Just as you said, some match what one would experience ingame, but since these are CBT values, it’s equally certain some are different now.

Some of them are certainly outdated, but there’s no reason not to add them because a lot of them definitely are still valid. It’s a nice point of reference.

Nice fix mate :>

I’m just expressing doubts that Brandish was EVER using such a high DPK value. Although if @Bald_Dad is correct about kill counts in channels not resetting after crashes and maintenances that could explain why the item was still prevalent in ICBT2, but I don’t recall any other DPK items being way more common.

I certainly wish DPK didn’t reset after maintenance. That’s pretty absurd. Actually I wish the system was thrown out completely, to be honest, it makes me hate other players.

DPK is a bullshit, can you explain how i got 2 shade runner recipes after i killed over 323 mobs then 1 more drop after 7 mob?

Found this a while ago but never bothered posting it here.

Depends, each channel seems to have their own DPK from what I’ve experienced, not shared across all channels.

If I stick to one channel and never switch, the drop rate for Yellow Gems and Storm Staff recipes on Medakias was entirely consistent with the DPK values, which then makes me question the code @Excrulon linked on reddit.

The code shown there still gives a ratio, an RNG number, a % as a return value, but RNG should never allow for exactly this or that many kills to drop an item without fail. People are able to outright predict monster gems. Back to my Medakia farming, I always got yellow gems a few kills AFTER storm staff recipes. I’d need some more explanation if it really isnt based on kill count because I have 0 reason to believe it isnt.

Eh yeah no idea if it applies for all dpk drop rates or just drops for quest items (believe that’s what this code in particular is for). Just throwing it out there.

That code is so confusing, to me it looks like a inicialization of a itemlist about a drop.

For people like you, i don’t share the good DPK for certain items on forums or tosbase, in fact, if i was OP, i would delete this thread, instead of helping scrubs like you having an easier time farming items on this game.

Believe whatever you want, we don’t give a f*ck.

lol u acting like you doing my work lmao, and I don’t believe this such bull crap if there something like that. The item that I farm shouldn’t be dropped 2 times in the same channel mate. This is just a theory, I don’t give a damn, but I gave my reason it is not working as DPK. You said u don’t give a ■■■■ but u reply I’m sure u give a ■■■■. I am not a gaming nerd who spent day after day to solve the damn program puzzle. I will give it a try another time to actually believe in this gacha stuff

Dude, you complain and you haven’t even read the thread. You haven’t even tried to understand.

Each channel can have multiple spawn mobs or groups. See for example, in tosbase, when a monster under lvl200 appears twice in the map information, it means there are 2 separate respawn groups. Each has their own DPK count.

Information after lvl200 is not reliable in tosbase cause it wasn’t mined in the same way.

Thanks for the info. Code pretty much goes back to my previous post:

We’re missing the bit where the point at which the dpk count starts after maintenance is assigned, but that’s probably part of the maintenance script.

The only way to confirm all the observations match the code output would be to check the live database in the actual server responding to the changes (kills, drops) in real time, but this seems really close to what it should be.

Majority of the people calling BS on this and claiming “how come, I got 2x or more of X-item in an X interval” haven’t bothered to understand what the thread is about.

AND YES, IMC HAS NEVER COMMENTED ON NOR CONFIRMED THE MATTER; THEY NEVER WILL.

These are mostly based off of early data gathered (prior to info being hidden server-side - EARLY RELEASE) as well as player based observation and testing on VERY SPECIFIC ITEMS (eg: Monster Gems). NOT ALL ITEMS. Especially not the new items.

Before commenting here, make sure you guys UNDERSTAND that DPK is not all-encompassing. Majority of the loots mentioned as rebuttal to the topic are non-DPK items, just normal RNG. A perfect (as of this time) example of a DPK drop are Monster Gems (make sure it’s from the same spawn-group as well before you refute that you got 2 in a row).

I remember someone posted a video of an incoming Monster Gem drop (with a written declaration that it will drop) because the DPK-threshold was about to be reached (and he was right).

It does not mean that everything found here is absolute and incontestable. IMC can subject their game/files to changes as they please with no prior warning.

Take what you can understand from this thread with as much grain of salt.

I implore to at least do your own testing before you start contesting.

AS THIS IS AN MMO, most of the data provided is in as much of a “controlled state” as permissible. Mostly after the server goes live after maintenance and preferably with a channel soloed. This is to avoid the data gathered from having any inconsistencies.

Of course, this is not always the case as you can’t really close off a field-map to hog for yourself.

Some even go so far as to try for a DPK-drop more than twice (which is the generic rebuttal used here) to establish a more consistent figure to limit discrepancies.

Eg: Obtain the “item” once. Set that as the starting point, then farm for it until it drops again, to establish the “difference” or “count to next DPK”, THEN do it again to see if you can replicate the results. Not once, not twice, but thrice or more until the pattern starts showing itself.

Of course, this is extremely time consuming and soul crushing, which is why the OP turned to the community to share their experience (provided they have unsullied data).

Hey man, remember about what I shared with you days ago regarding my experience with farming from Yellow Coliflys?

I’ve only been able to look it up in TOSbase now:

Ruklys Hall of Fame (55, 30s)

Does that mean only one spawn group in the whole map?


According to the map info, yes, but as I said before, information about maps lvl200+ doesn’t seem to be accurate since it wasn’t mined in the same way or at the same level of detail than it was during iCBT. There are some maps with multiple listed spawn groups of the same monster, so I’m inclined to think it actually is just 1 group of Yellow Coliflies there.

You were changing channels too, so it’s a bit harder to determine who was where and how many were killed before the next item dropped.

Do the running kill count reset when the player who was doing the killing changes channel?

I mean, if I’m the only one there in all 3 channels, and if what I said above doesn’t apply, my running kill count per channel should still continue as soon as I go back to that channel.

Why would it reset? It’s bound to the mob you’re killing, not to the character. This was tested by having a different player kill the last few monsters before a dpk item dropped (can’t find the post right now, but it’s here).

What I do know is that the number of players in each channel the game reports to you is delayed and/or inaccurate. I’ve been in a channel with 2 other players while the game tells me there’s only 1 in there. Most recently I was a=in Alemeth doing my quests and a full party were clearing truffles and the game reported 3 players in that channel for the next 3 minutes, then zero… and I was still there.
