Please help me to create a new icon to reflect my new combined Lore skill

[Legujox 0]

Hi, my name is Leo, been playing on and off Sacred 2 almost since release ( just realized it's more than 10 years ), and a little of Underworld before that. Recently, I bought the Steam version and download CM patch and the awesome EE, and I like it a lot. Liked it so much that I started changing a couple of things on the notepad, modifiyng some spells, icons and other values, etc. Just to twink it to my liking.

Now I want to modify skill icons, but I can not find where they are placed, I swapped CAs icons before, but can't find the Skill icons on the rar files.

My plan is to make 2 spell Lores depend from only 1 Skill, inspired by Shadow Warriors's Tactics Lore, for example, merging Celestial Magic Lore with Revered Technology Lore, and ofc, changing the spell asociation and everything to make it work properly and I want to create a new icon to reflect this combined Lore skill, just to add a special touch.

If anyone can point me in the right direction, you will make my day, thank you!

Sorry if there are some grammar mistakes or things like that, I'm from Argentina and english is a second language to me.
