For anyone who gets frustrated when trying to get a +10 weapon use this method: By weapon, enchant to level 1, save, attempt to enchant to level 2, save if you succeed load if you fail, continue until you get level 10. It's a bit cheap but it saves you huge amounts of time and money.
Sirboomalot: I don't think that second one's really a combo. Anyway Otyugh, boneyard, bone wall, everything you eat gives you another thing to eat and prevent two more attacks.
By the way I have a (reasonably easy) trifecta challenge for you: 15 hundred dollars, 15 thousand seconds (that's 25 minutes) and 150 thousand feet, in one launch.
This is ridiculous (and I'm not even talking about the scientific errors) I got to over 150 thousand feet then stoped trying, it took me nearly 15 minutes to get to ground (5 were just going left as fast as a could before i realized that i was only going down about 2000 feet every minute).
Persian: (assuming you're speaking of survival) No shop, no pause. Every time you defeat a wave the next one comes and the actions continue according to quickness (it doesn't go back to highest first, that's important) there are 20 set (as in non-random) (5 for each enemy number 3-6) with a boss among the last wave of each number of enemies, every 20 levels repeats. This is the case as far as I've been (in the 40's).
