After some careful consideration and some more testing, I have upgraded this spellbook again so i have room for wardstones. Also, i figured that since i have acid balls and force pushes, i might as well include a wall of thorns as another source of damage.

Also, while more armor could help, i'm not sure how necessary it is. while some attacks can still get through, it gets increasingly less likely over time. I think people underestimate defenses because they're luck-based. However, all attacks in this game are luckbased, since all damage is decided by die rolling. And with two Temples of the Dawnbreaker and a Defense Ring, the chances of an attack targeting me when i use a defense is really low. Furthermore, with Temple of the Dawnbreaker you can reroll failed defenses AND attack rolls you don't like that target friendly creatures. When your armor is pierced, you don't get to reroll the piercing effect; it's already too late. Furthermore, Defenses can't be corroded. That's why I have a second Dancing Scimitar instead of a second Dragonscale Hauberk. Don't forget to check out my spreadsheet! I put some good work into those calculations.
