I'd love it too I use the tools for most everything. I upgraded to RoF and the spell importer tool worked great for UF but I am a little afraid of ending up like some who've posted in spells support about breaking all their spells by trying to edit.. I trust his tools more than I do me doing it
I know u are supposed to be able to run source/utils/script/import spells pl and use your RoF spells_us text somehow, but I personally do not know what I am doing on that yet.. if anyone does know I'd love to hear about how to do it correctly but otherwise even more so I'd love for George's to have RoF option on the spell importer with updated spells, my mage pet is 70 for level 85 atm..
