I'll try to keep an updated list of mods here that people enjoy with Adventure Mode. I'll try to edit in any suggestions posted in the thread as well, as long as they enhance AM and work properly.

While some mod setups may require further adjusting the load-order in the launcher, the general guideline is to put these mods above AM and others from the Torchlite pack then adjust if needed.
