I am planning on buying skyrim for the pc after playing on consoles since it came out and a major reason for that is the loot. I want to actually have a reason to go into caves at a high level such as finding awesome mod loot. My question is, if I download a weapon or armor mod will I be able to find those as loot and on enemies or no? Im sorry if im posting this in the wrong area but I have looked everywhere for an answer and I am really curious.

Some mods add their items to the Leveled Lists. So yes, it's possible.
