"This spell gives the caster the ability to switch to another spellbook that they have access to and cast one spell from it. When a player casts the spell, they are presented with a choice of the spellbooks they have access to. When they select one, the runes for this spell are spent, experience is granted for it, and the player has two minutes to cast one spell from the selected spellbook. They will return to the Lunar spellbook once they cast one spell from their selected spellbook or if two minutes have passed."
While doing vorkath I wanted to use venge and cure me while spell book swapping to crumble the undead. Then I found out the spell permanently swaps your spell book when it shouldn't, would love feedback.
