I just heard about this recently and i've been wondering. I'm going to be a bishop soon and i'm now worried about overleveling at skeles later in late game and not being able to sell leech cause of being overleveled.
It really depends, selling low level leech is way less profiting than high level, you'd just have to choose which kind of leech you want to sell and go for it. If you want to sell low lvl, you can just buy a charm and even stay at lvl 120. Recently people seem to be buying for 80m/hr which is nice but you have to consider the lower drop npc price that also should come into your calculation when figuring out how much you make per hour. If you want to sell high level leech, you can either level while selling low level or figure out a way to level, but you might have to invest in things like gen 20 and equips to be able to sell proper leech(1 hit at high level places), which could yield greater amounts, even without the drops.
I will most likely be aiming to sell skeles 1 hit. What if I overlevel to like 170+ or something? would a lvl 150 1 hit seller (for example) have very high priority over me or it's not that much of a difference? Thanks
I'm a low level leecher so I was able to provide you my 2 cents on it, unfortunately I can't help as much for high level leech. Although I think the level isn't a big issue in late levels, but I can't say for sure.
The level does make a difference how much the leecher gains but it matters more how well the leecher plays. but you cannot know how most leechers are (with the exception of a few who are commonly known since they sell very often) So level is the only indicator of how much exp you will get. Low level leech matters the most about level. A level 156 BS trying to sell you muddy banks will eat your EXP. tl;dr if you're a reputable seller it's whatever: if you're planning to just sell it from time to time; people will judge you more.
I sold stuff like skele and petri leech at lvl 190+, you just have to charge a bit less (like 60m for petri or 50m for skele)
Is all depend of the buyer to be honest.. most of time when i'm leech (on my I/L 17x) at petris i didn't have a bad answer from the buyers. However as far as i know as a high level will consume a little more of exp since the high difference of level. Maybe 5% to 10% of each kill you do. Anyways as leechers we need to always give the right to our costumer :3
