Mage Leeching in Old Maple and Will Classic Have It

Sometime around 2007 a level 130 Bishop in our guild stopped answering party invites. She was not gone. She was standing on the top platform of a Skelegon map in Leafre with Genesis on cooldown, a stranger's level 70 Hermit sitting on the rope below her, and 30 million mesos more in her inventory than she had the day before. That was leeching, and for a couple of years it quietly reshaped how people levelled in MapleStory Classic's source material, the pre-Big Bang game.

If you are coming back for Classic, or coming in fresh, it helps to understand what leech was, why it worked, and why it might or might not show up again.

How party exp actually split

Old Maple's party exp formula had two parts. The player who dealt the killing blow got a base cut, and the rest of the exp was shared across party members on the same map, weighted by level. Higher level members took a bigger share. Crucially, you did not have to hit the monster to receive exp. You just had to be alive, on the map, and in the party.

That last detail is the whole business model. A level 30 in a party with a level 150 got a small fraction of each kill, but when the level 150 is killing a full map of Skelegons every ten seconds, a small fraction of a lot is still more than anything a level 30 could earn on their own. Nexon later added level range limits for party exp, and the exact numbers changed over patches, so if Classic uses an early build the rules could be looser than what people remember from 2009.

Why it was Bishops and Ice/Lightning

Two classes had the tools. Bishops got Genesis at 4th job, a full-map holy attack with a long cooldown, plus Holy Symbol, which boosted party exp by a large percentage. A Bishop could clear a map, sit through the cooldown while the leecher sat safely on a platform, and repeat. Ice/Lightning Arch Mages had Blizzard for the same job, and before 4th job existed, high level I/L mages could already farm with Ice Strike and Thunder Spear well enough that people paid for it.

Fire/Poison mages could technically do it too, but Skelegons resisted fire, Himes were less convenient for them, and the market settled on the two classes that cleared fastest. If you want the long version of why mages were a strong economic pick in old Maple, our class guide covers it.

The typical spots

Spot	Monster	Who bought it	Rough price we remember
Leafre, Skelegon maps	Skelegons	Level 90 to 130	Tens of millions per hour
Showa, Hime maps	Dreamy Ghost (Hime)	Level 70 to 100	Somewhat less
Ludibrium side, Warped Path of Time	Wolf Spiders	Mid 60s	Cheaper, less popular

Prices swung wildly by server and year, so treat that column as a memory, not a fact. What did not change was the structure. Bishops advertised in the Free Market, in guild chat, and on forums. Buyers paid per hour, sometimes per Genesis cast, sometimes with a discount for bringing their own Holy Symbol mule.

The argument nobody ever settled

The community fought about leeching for years. The case against it was simple. A level 120 who leeched from 70 upward could not play their class. They had never used their skills under pressure, never learned their maps, and showed up to Zakum runs as a liability. "Leeched" became an insult. Guilds sometimes refused to recruit anyone who admitted to it.

The case for it was also simple. Levelling a Cleric to 120 was slow and lonely, and selling leech was the only reliable income for a class with weak solo damage. It funded the Bishop's own gear. And for the buyer, if you had already levelled three characters by hand, paying to skip the grind on a fourth was a reasonable use of mesos. We ran a guild that took both positions at different times, depending on who was loudest that month.

The honest answer is that leech was a symptom of the exp curve. When levelling from 70 to 120 takes hundreds of hours, people will pay to shorten it, and the game gave mages a way to sell that. Nexon knew and mostly left it alone.

Will it exist at Classic launch

This is where we have to be careful, because it depends on three things Nexon has not confirmed.

First, whether 4th job is available at launch. Without Genesis and Blizzard, leech at Skelegons does not really happen, and third job I/L mages selling Hime leech is a slower trade. Our 4th job post has our guess on when it arrives.

Second, whether the party exp formula is the early one. If Classic uses a later pre-Big Bang build with tighter level range restrictions, low level leeching is much less efficient.

Third, and this is the boring one, whether there are enough high level mages to sell it. At launch there will be zero. Leech is a mid-life phenomenon for a server. Expect it to appear, if it appears, once the first Bishops have reached 120, whenever that turns out to be, and expect them to charge a lot.

If you are planning to buy leech later, remember that it is a meso sink. Some players will fund it by farming, and some will buy mesos from shops like ours, knowing Nexon's rules forbid it and that accounts do get banned for it; our honest take on buying weighs that properly. Our own view, for what it is worth, is that the first character on a fresh server should be played by hand. You only get one first Zakum run where you actually know what your buttons do.
