Eternal Essence – Faster AI turn + smarter AI.

Hello, I wrote in this thread some time ago, but my message went unnoticed, so I'll try again.
I would like to know how to make it possible to have 8 skills in Campaigns; someone seems to have asked before, but didn't receive an answer.
I thought that it would be simple if the mod (if you can call it that, but I think you can) was permanent and not activated.
Although I am not very skilled, so I am not sure.
