Glad I could help, even in a roundabout manner.Fixed in the next version of the core mod. Thanks for reporting, albeit in a roundabout manner!
Aegis really is straightforward, but I love the note on the reel when it pops up! It really is mildly insidious if you're not really paying attention and suddenly you're taking full damage again.
I've only gotten the tome once, and I proceeded to accidentally kill myself with the micro missile... machine gun... thing. Skyblotter, I think?
The alternate mob reels are also real good. I've finally figured out which pirates I need to watch out for to avoid being set on fire constantly. I'm really excited to see what else you have planned.
I've yet to survive mini boss mode, but it's also just good, chaotic fun.
