I almost hate to say it but after getting my ass handed to me for the umpteenth time I just used an editor on my save file. It's amazing how much easier it is when you're 99th level with max stats and an ungodly number of full heal potions. It did make the demon area easier, but less entertaining, but the overall game wasn't too bad. My one serious gripe, besides the sudden jump in difficulty, is the names. Spikedo? Seriously?
Can you please tell me of the save editor you use? Never used one before, so id love to try this out to get off this annoying part. Otherwise ima just drop it.
