I've played on Normal Mode to get pretty much every achievement [excluding No Exit in Sight and Wand of Amethyst because they take so much time to do] and I can't seem to get Master of All. I've bought every normal item/curse, and tried to purchase all the temporary items [such as Party Hat] but I can never seem to get the achievement no matter how many buy. Is there something I'm not getting and/or missing? It's one of the last achievements I need to get [the others being "BONK!", "By the skin of my teeth", the aforementioned time-consuming achievements and the black achievements]. Any tips would be appreciated!
