Option Paralysis Touch

My current Pathfinder campaign is reaching end game and I’m suffering through the pains of high level NPC spellcasters. Picking an action out of dozens of prepared spells and tracking slots after the villains spend six or seven rounds buffing is tricky. There are a lot of potential actions and combos to consider. And there’s the irritation of having to look in two or three books to figure out what each spell does. I’m making regular use of spellcards to keep track of abilities.
