How to edit .pak files on Aion 2.5

Credit : Mr. Rajin

Hello Guys,
as a lot of people wanted to know how to edit .pak files on Aion 2.5 I will give a little tutorial here.

All Examples will be on Skills.pak (you need WinRar installed)
How to edit .pak files on Aion 2.5 The first thing you need is aion_extract:   aion_extract.rar (851.14K)
Just start the program and select Skills.pak file and an output folder (eg Desktop/Skills) and extract it.
For people that want an extracted, clean client_sklills.xml:   client_skills.rar (445K)

Now if you look in your folder Skills there are hundreds of .dds files (those are skill icons)
and some .xml files. Search client_skills.xml and open it ( it would be best if you open with notepad++)
Now I will show you (on the example of Sigil Strike VI)
how to remove chains (so you can use the skill everytime)

To find you skill in the xml go to Aiondatabase.com and search your skill.
In your browser you will have something like this "http://www.aiondatabase.com/skill/936/sigil-strike-vi"
The blue number is the skill ID.
In Notepad/Notepad++/Whatever search for this ID,
then you will have something similar to this:

<skill_category>SKILLCTG_CHAIN_SKILL</skill_category>
<ultra_skill>0</ultra_skill>
<ultra_transfer>0</ultra_transfer>
<chain_category_name>SRA_ChainD_2th</chain_category_name>
<chain_category_level>6</chain_category_level>
<prechain_category_name>SRA_ChainD_1th</prechain_category_name>
<chain_category_priority>AS_CarveSignetChain</chain_category_priority>
<chain_time>3000</chain_time>

On every chain skill you find these lines.
Remove the red ones.
Save the document, and now we come to the part that is different from Aion 2.1

We have 2 Options:

Go Into the unpacked folder, Hit CTRL+A (to mark all files)
Right Click them and select the WinRar Option "Add to Archive ..."
Apply this Settings (ZIP format, Name: Skills.pak) and click ok.
Now go to you Aion/Data/Skills directory and move the skills.pak from there to another folder (e.g.: Desktop/Backup)
Take your new Skills.pak (from Desktop/Skills) and put it in the /Skills directory.
Start Aion -> Have fun

Go Into the unpacked folder, mark ONLY client_skills.xml
Right Click it and select the WinRar Option "Add to Archive ..."
Apply this Settings (ZIP format, Name: zSkills.pak) and click ok. IMPORTANT: Name must be zSkills.pak
Take your new zSkills.pak (from Desktop/Skills) and put it in the /Skills directory (do not remove the old Skills.pak).
Start Aion -> Have Fun
