@DavidCoffron: I took a dive into the PF system of spellcasting in that linked question. It was a bit of confusion initally about version differences, and then bemusement that the mechanics of the game allowed for this sort of thing
"It's terribly complex, prone to failure, and can fail if you take damage but nah it's fine you can cast two at the same time they're pretty easy" is just an interesting concept
