My long time rage playing various megamods is seeing those unpolished spells in game. Almost all the big mods for me are unplayable because of that. Also i don't suspect to learn everytime new tactics with new spells, which varies with those mods.
Is there a some way to install big mods and keep default cleric and mage spells? Overwrite the changes at the end of install? Changes to default spells are ok, how could i avoid new spells in the game?
