Re: Berserk aurora
I guess you can make the beserk spell last very long, that's pretty easy to do.
Open SPECIAL_ABILITIES_BERSERK_DEF_INSTANCE and find 3AFC7DF4 - Beserk Duration
Change the number to something high. Don't know what the max number is, but you can experiment with that. I'd start with something like 99999
Now if you'd only want the aurora, you could delete all other effects (the color change, the bulkiness etc).
