After careful, diligent curiosity I have found that 30% of the players of this game are unrepentant hackers that somehow don't get perma-banned by Nexon.
After further diligence I have discovered that some of the end-game bosses are mathematically, scientifically impossible to complete without hacking. Thus, Nexon requires hacking at end-game. So learn how to hack. Nexon loves it.
Jenn is about the most incompetent locksmith I have ever seen. He needs over a half metric tonne of metal to forge a key that is 2 oz in weight. Why does he need so much metal and where does it all go? Honestly I think it's just a big con job and in that case I should be able to just kill Jenn off for being a rat fink lowlife.
Please reduce the requirement to something sane and fix the looting speed. The whole of Lion King's Castle (Simba!!!) has this atricously painful loot speed of less than 2 per second if you spam the button. Sure, it encourages folks to buy a pet but for folks who don't have the NX or moneys to spare at the moment it's like trying to pick up 200 objects as slowly as possible while things try very hard to kill you (and do a great job of it. They hit HARD out there!)
So yeah, Jenn only needs 1 hat, 1 spear and 1 morningstar. Really. That's it. He can make like 200 keys with each of those things. He should be able to forge 40,000 keys with 200. Seriously. Send that guy to Lock Smith school.
Botting is typically a hex editor or cheat engine thing. Most times it's done by tampering with the signal between the client and server but sometimes it's just messing with the client. This is part of why so many people get Legendary Potentials so fast. They force the cube to upgrade the potential and go from Rare to Leg in 3 cubes. Then they force the Starforce to Success each time. Then they bot like mad and meso farm ultra fast because every monster is sucked to them, they cannot be hit by monsters, and their pet soaks up all the goodies at light speed.
Nexon could watch for critters in "unauthorized" or "abnormal" locations (there aren't many classes that mess with mobs' map location and they are limited in where they can move the mob) and flag the map that it's happening on for a GM to have a look. They could also look for "excessive looting patterns" that are impossible in legit play (such as uninterrupted meso grabbing over a period of 30 seconds) and kills that happen too fast for too long a period (e.g. 2 or more kills per second with no interruptions for 30 seconds). They could flag certain characters as "legit badasses" so they don't constantly get drawn to the maps that they are wrecking mobs on while keeping the detection on high sensitivity to pretty much instantly pick up on hackers/bots.
There are many ways to go about it and most of them are small scripts that use very little processor time. Nexon just doesn't want to catch botters is all. They like hackers. Otherwise this game would have a LOT less of them. "Just don't get caught" seems to be their motto by what I've seen. I could be wrong though and Nexon could just not want to chase hackers down because they would rather make more content instead.
It seems like the Meunster Manwell for this game (facetious misspelling intentional, 2 references: one to cheese and another to Wall-E) uses a controlled form of *rnd script to determine whether you get the critter added to your Pokedex. It seems to be a conjunction of kill threshold and a % chance after you meet the kill amount.
And example of what it appears to work like: Kill 999 Qualm Guardians then a 2% chance to add the next kills to your Monster Bible. Not an actual function because I really have no exact idea, just an example to show how I think it works.
I did notice while playing that the Kill threshold is account-wide so you can kill 998 McDerpapotomus Plerps and then get that last 1 kills to meet the minimum amount then manage to score that 1% chance right off the bat with kill #1000 on your other main or whatever that gets added to your ManStair Collection.
