Finally I reached 15th floor and met Lord Dredmor for the first time (Dwarven Moderation + Permadeath). I tried to fight against him but some of his magical attacks do an insane amount of damage (more than 60, almost half of my total life). Furthermor Dredmor has a lot of HP.
I obviously died, at least I got an achievement.
Now, I would like to try again. Can you please give me some suggestions about which skill trees and which skills are more effective against Dredmor and some tips to use when I fight him?
Best Answer
I managed to get to the bottom of the dungeon and off Dredmor on max difficulty with permadeath on. I documented my entire strategy here, but I'll summarize as best I can.
I suggest you grab the expansions if you can, it's only a couple of bucks and it adds some new stuff that is worth having. That said, don't turn on the Diggle Gods levels, and don't take any portals to the Wizardlands, as both of these are just going to increase the odds of you biting it.
My skills were:
Master of Arms, Perception, Burglary, Unarmed Combat, Battle Geologist, Alchemy, and Smithing.
Battle Geologist requires an expansion, and Smithing was kind of underused in this build, so I provided some backup skills for your consideration in the full guide. I'd almost suggest a ranged weapon tree of some sort.
This is a very "tanky" build, where you're going to focus on defensive stuff. Dual wield shields, and focus on Block, damage resistance, and elemental resistance. Learn to exploit the AI to trap it in corners and halls where the enemies can't surround you. This will get you through the majority of head-on encounters.
For very deadly fights, especially against magic users, (such as Dredmor himself), you're going to want high amounts of sight radius. If you can find a spot where you can see these guys at range but they can't get close to you, you can plink away at them with thrown weapons or crossbows. Failing that, the Perception tree's Eye Lasers do decent damage, and they don't require mana to use.
You can also use Burglary's Lockdown ability at range to hold them still and get away if things are looking bad. Burglary's "Lucky Pick" ability also means you can close all doors (ie, you're not bashing down locked ones when you're out of picks), so prepare to immediately close doors once you open them. Finally, save items of invisibility, which are good "panic" abilities to have on hand when you're at the final level.
