I, on regular terms, have at least 15 detect invisible preps. I had been running around, recently, though, with lacking gear, coin, etc. I forgot at that point, being as I thought I'd be fighting Ragers, not an invisible Lich army.

Flight potions? I used to carry them around. I don't anymore. It just feels like a waste of time, honestly. I spend time getting it, I die, there they go - Wasted.

I can assure you that I do read all of the comments, as I'm trying to learn.

Thanks for being helpful(To everyone except for Yhorian. Suck it, Trebek.)
