Okay, so I've beaten the sepulcher three times now. It's not as hard as I first thought, you just have to keep moving and find another light source. Seems like it's a short cut to the clock tower. I also got the infantry grenade and a rune (forget the name) that when combined makes mobs drop blueprints. Still haven't gotten the spider rune, but did get vampirism, impaler (great weapon), Valmont's whip (another great weapon), and a few other blueprints to drop now. I can get to the castle on a fairly regular basis now, but I keep getting smashed by the mobs when I get there. Think they're tuned a little too tough, as even when I have 5k+ in hit points, I'm still getting face raped. My enjoyment of the game is waning. Starting back at the beginning every time is getting annoying, and you really can't afford to skip mobs and rush to the next board because you won't have enough power ups to defeat the last few boards anyway. Fun game, but I wish you didn't have to start from the very beginning each run.
