This is as you should be able to guess my jester version.

The builds I will suggest is the builds with the highest damage per second (DPS for short) thus making it a faster levelling build than the damage per hit (DPH for short)

I do know this doesn't include anything for teh bow using jesters. for that part ill advice you to look at my ranger guide for a more detailed reasoning.

And all DPS builds is 100% crit (or pretty damn close to it at least).

Now before we start the actually build making I will start out with what equipment to use from level 15-120

Now we start out with our little acrobat at level 15 and already here can we get into some nice equipment (note I will state the sets that has an effect worth going for to
A. make it cheaper
B. make you kill faster)

So the set we get here is called:
Stinger/Slepint
Effects: +36 def +3 Dex +10% fp +10% Crit rate

This set I recommend using from level 15-60

As for weapons none of them actually has any effects worth mentioning so just change every 15 levels or what ever yoyo that takes your fancy

Level 60:

Now you have become a Jester so lets make a short summery about them.
The Jesters special ability is getting 4x as much crit% as all other classes (4% every 10 dex)
Furthermore they get a self buff all other classes envy: Critical Swing +40% crit (in jester language that means 100 less dex, in all other class language it means 400dex)
This comes at the cost of no aoe moves though so 1v1 is the only way.
Also yoyos gains damage from str

Now we know that crit will come easily so we need to focus on 1 thing and that is Additional damage of critical hits (ADoCH for short) and luckily we have an acrobat set with a great effect right here, the level 45 set called:
Hyper/Crusier
Effects:
+55 def +11 bow power +10 yoyo power -20% mp consumption -20% fp consumption and +40% ADoCH

So we shall now use this set
As for weaponry you can get the Guardian yoyo for a neat damage incease but its not needed sicne we will soon be changing to our end game weapon

Level 75
Here we will get 1 thing only:

Our end game weapon:
Historic yoyo:
+7 Dex +28% ADoCH

This yoyo even beats the bloody yoyo so this is what we will use forever

Now we level some more and hit 90

Here we get our end game set:
Rasra/Restra
+49 Def + 15% crit rate +40% ADoCH

Now for a short summery
At end game your Jester should be using this:
Historic yoyo
Rasra/restra

A grand total of effects is:
+7Dex
+49 def
+15% crit rate
+68% ADoCH

Now we still have a few things to discuss:
Jewellery
Capes
Awakenings
Build

Jewellery is easy
2xVigors
2x Demol
Peision/gore (I prefer the peision because the master skill eats a LOT of fp and hp isn’t that needed)

Capes
Well here we have a lot of different things to chose from and any cape that adds a high number to all stats is a win since you can remove more from Dex and throw it into Str (example: dragon cloak 4 adds +14 to all stats thus you can take 14 dex from your base build and throw that into str)

Awakenings is simple as well
We need more ADoCH. No 1v1 class can ever get enough since this multiplies our damage by a LOT. So get as much as you possibly can and watch your damage skyrocket

Build
Now this is probably what you where looking for. But now class should start messing with their build before their equipment is done.
However here we will play with the fact you have clean equipment and don’t use a cape (meaning no awakenings or upgrades on you set)

We want 100% crit as a 1v1 but first we take out what we have from buffs
100% - 40% (critical swing) =
60% - 8% (cannon ball) =
52%
Now we take out rasra/restras 15% and we get 37%
Now we have to think a bit
37 isn’t dividable by 4. 36 is however
36/4 = 9
So we need 90 dex.
Take out the Historic yoyos 7 and we sit with 83dex

Thus making our build:
83 dex
xxx str (xxx = rest goes here)

now come your turn to customize your build
with awakening and highly upgraded sets

and as for a few final words.
This doesn’t really include anything for people rebirthing since you will reach your build before you even hit level 60
And now
Enjoy your new Jester ^^
