Apocalyptic Difficulty playthrough. I spend all my skill points on Exhume first, then on Teleport Slash for first 98% of the game. I then switch to Unstoppable and Aegis Guard for the last 2 Boss Fights. I collect every Book of the Dead Page (and note when they appear for each video) to open all of the Death Tombs. I also complete every side dungeon as they become available. The only other side quests I complete for XP are "Spark of Life", Hammer's Forge", and "The Lost Soul". I don't complete any others because they only reward special weapons that aren't necessary for completing the campaign.
