I see. Then, could it be possible to modify PRC so i can use that build? If so, how can i do it?
Extract cls_pres_palema.2da from prc_2das.hak and open it in notepad.
Change line:
0 ScriptVar VAR PRC_ArcSpell3 0
to:
0 ScriptVar VAR PRC_ArcSpell2 0
(for 2nd lvl spells you need only 3 lvls of wizard, so this will work for that build)
save the file and import it back to prc_2das.hak or place in other hak above prc_2das.
