Ars ‘n Spells Mod connects Ars Nouveau and Iron’s Spells ‘n Spellbooks into a shared magic system. It combines mana pools so both spell types draw from the same magical resource. Equipment, robes, and curios boost spellcasting across both mods without conflict. Players can write custom spells onto scrolls and cast them directly from an Iron’s spellbook wheel.
