I'd suggest you open the propskill.txt.txt and find the name of the Skill in this case "Blessing of War" look to the left you'll see an IDS copy this tag and search it inside of the propskill.txt
This is how mine looks, if you're missing the skill add it by hand, Warning don't just copy and paste mine, My source could be pulling more tokens then your source, will crash worldserver if that's the case.
I've not seen any programs that still work I've just done it by hand with notepad++,
I'll try to explain each line as I remember or pull from a guide
example
Note that the values inside the () are pulled from the Spec_item.txt for that line, the
AddVendorItem pulls all items that are defined with these values.
but I'm sure you can figure it out with a bit or messing around....
6thas for the question in regards to the skills simply read through the skill on the propskill.txt find what you need to change and change it...

If you're looking to change rates and stuff get your hands dirty open every file inside the resource folder and look around.. I can't help much here as I don't really recall myself, all i do recall is PierceingSize.txt, accessory.inc and itemUpgrade.lua

Get a better source?
this should work out of the box unless you damaged something or the Spec_items for the IK1_ IK2_ IK3_ on that item has been changed or the file handles a different token that was also changed / messed with....
