DISCLAIMER: I do not own, developed or helped to develop this tool in any way, shape nor form.
Whomever the original creators are, thank you for such a great tool, now to the task at hand.
Since the release of the Gunslinger is around the corner, the topic of build(s) came into play, so with some searching around i came across a JP skill simulator that has skill simulation for all the classes...(yes, even Soullist) and even some other neat, unique and interesting features. I will try to explain the tool and showcase it to the best of my ability.
First of all the URL for the tool is: http://orange.pepo.jp/c9/
Notice the first SS (Firefox) has the skills in japanese while Chrome translated the skills/ site to english which makes it easier to use, however chrome does not load all the elements on the page which i indicated with the red square. That section has tabs which make it able to filter out Action/Command/Passive Skills and shows the amount of remaining SP. Although the translated Chrome version doesn't allow filtering, there is a small workaround to check remaining SP but we'll get to that later. I recommend using the Chrome (translated)version unless u are familiar with JP which by all means have a field day lol, but for English speakers like me using this with chrome is your best bet.
In Chrome the buttons at the top still show and are fully functional:
Reset - resets the skills back to zero/default learned state.
Output text - this button will bring up a popup textbox with the skill and correspnding levels as to the current simulator build. Additionally this button is a workaround to check the remaining SP also.
Output URL - creates a URL/webpage to publish or share your build if you'd like to.
Nonsense - in essence a "changelog" for the tool.
L/S - changes the size of the skill simulator icons to large or small respectively.
Class Drop-down Box - Drop-down box to select desired class.
Build Name Textbox - Textbox to name the build.
The tool is very well designed and rather complete imho, neat features and accurate, id recommend anyone to use it, whether new players or experienced ones, especially now since the skill simulator2 that was in development seemed to have stopped. The only thing that I would change on this tool, is the ability to select level and continent, SP quests etc like the older simulator on c9.mmosite.com, however the tool was build to accommodate all of wat was mentioned up to level 63 and up to the 5th continent (Sarad's) SP quests so you have the correct 1555 SP available to use.
So yeah, thats basically it, anything not clear or if you think could be explained better, leave a comment or pm me and once again the link http://orange.pepo.jp/c9/
TL;DR - All Classes skill simulator, http://orange.pepo.jp/c9/ copy the link and open in the Google Chrome web browser which will fully translate the page to English.
