C1 > P3 > Pardoner 2:
Buff selling provides very little income unless you are in the absolute top percentile of Pardoners on the server. Unless you are full SPR, have full SPR gear, and are at the very least Rank 8 but preferably 320~330, you will find that buffs move very slowly. You’re probably looking at tens of thousands of silver per week.
You can however make a bit of money off of Dispeller scrolls, which you can make at Pardoner 1. They don’t move too quickly, but they do move regularly, so it can be a great supplement to your income. Also, having your own buff shop to use saves you a good chunk of money if you don’t mind not getting the optimal buffs available. All in all, I wouldn’t really recommend it as a way to make money unless you are willing to really spend a lot on getting it set up - and even then, it’ll take a considerable amount of time to make that investment back, let alone profit off of it.
A2 > R3 > SR3:
This takes very little investment to get started (aside from the time spent leveling the character to SR3). The more you invest, however, the faster it’ll go. That won’t really improve the amount of money you earn, since dungeon entries are limited, but it’ll make the cash grind more bearable. The only gear you really need is Cafrisun, and then everything after that is your gun. Crossbow, Headgears, and Accessories will help push you a little bit further, but the pistol is really what’s doing the heavy lifting here, so after Cafrisun that should be your main investment.
This is really something almost any class can do, but SR is particularly well suited for it thanks to its high mobility and not-completely-terrible AoE. It’ll feel like a slow grind until you get well-geared, but its still solid money and the chance at a Petamion every time you run the 140 can certainly make it worth your time.
W2 > L2 > T2 > Featherfoot 2:
-Linker uses a skill called Joint Penalty to connect mobs together. While connected, whenever one of them would take damage, they all take that damage instead. Then, they use Hangman’s Knot to pull all the mobs into one place and stun them temporarily.
-Thaumaturge uses a skill called Swell Body to…well, swell the mobs. This increases their EXP and Drops by 2x, but also doubles their max HP (and heals them by the amount they gained).
-Featherfoot has incredibly powerful single target damage that is further boosted by Linker attributes, on very low cooldowns. This damage is high enough to overcome the doubled HP from swelling the mobs.
In effect, you get double drops, double silver, and double(ish) EXP from all mobs you kill if you pull off the combo right. This is typically used to farm high-end rare materials that can normally take multiple hours to find - doubling that makes your time investment much more reasonable.
The problem with this build is that you have no way of really dealing damage until Rank 7 (about level 225). Until then, you are relegated entirely to support. Thankfully, however, Linker and Thaumaturge are excellent support classes, so you will have no problem leveling at all if you have a party. If you are playing solo, you will probably be relying almost exclusively on Siaulai and Dungeons to level.
