In terms of damage, the builds are as follows:

Pure INT > INT/AGI > Standard Throwing Jester > STR/AGI > Standard Combo Jester

Pure INT jesters do the most damage, but they will always need a priest to give them accuracy buffs. Therefore, they cannot solo (at all). INT/AGI jesters can solo, since they have their own accuracy. They can solo easily until about 120. STR/AGI jesters are generally weaker, but their combo damage comes pretty close to throwing damage. They can solo easily until level 100.

Jesters require Seal Online Cegel  when they do not follow standard builds. This means costume sets and G gears, and that means Seal Online Cegel. If your jester is your first character, it might be wise to pick a standard combo jester build (meet requirements for armor and rest into STR/AGI). Combo jesters are the cheapest build.

CRAFTSMAN  (kajishi)

This is the blacksmith/crafter of this game. However, unlike in many other games, craftsmen tend to drain Seal Online Cegel when they're crafting and/or refining. Their specialties include cooking and weapon/armor/accessory crafting and refining. The most notable characteristic of craftsmen is the ability to add G, DG, and XG attributes to items. Not only will it remove stat requirements needed to wear these gears, but it will also increase their effectiveness and help immensely.

Unfortunately, crafting and refining success rates are very low. Scrolls are also rare, hence the reason why you won't find many G items in stores, let alone DG or XG.

The main stats you'll be leveling as a craftsman are STR and LUK. STR affects the power of your attacks and LUK is needed to wear equipment and make use of craft scrolls. The ratio of distribution to these stats varies depending on the type of craftsman you'll make.

Equipment-wise, you'll be gaining - stats from early equipment, mainly to your attack speed and accuracy.. These items will decrease stats that you desperately need to survive as a craftsman, namely Hit Rate and Attack Speed. Most craftsmen wear costume sets (especially ones that add attack speed) and hammers with no requirement. For accessories, wear anything that increases accuracy, attack speed, or both. Later on, the stat reductions from armor will be less, so don't worry about having to find costume sets to last you.

Craftsmen have a couple of attacks with accuracy boosts and high damage. Deadly Blow is the first one you start with, and a powerful one at that. You'll be gaining 30 levels using this until you can get your next attack skill, but be aware of the fact that damage from the level 30 skill doesn't stabilize or max out until a little bit later. However, it can do critical damage. You'll also get some nice AoE attacks later on as well. Don't worry too much about the bomb skill - bombs are too much of a hassle to craft.

As a craftsman, you'll be gaining quick levels early on, since you can train on many difficult monsters (provided that you have a priest or HP potions).
