i think from my knowledge of the game to get the TH acheivment/trophy you need to have had every item in the game at some point but what about the one time only items that can be upgraded, i've played game well into my 70-80 hours and know my way around i know what i can and cant kill i know roughly 90% of all items but im confused about items i maybe hvent had, so im looking for help from an item expert:?to tell me what one time items there are and IF they upgrade into somthing i am or am NOT able to get later on.
cheers for any help given.
