**Screenshot taken, but may not be the correct icon.
The materials I have screenshots of are starting to get uploaded now. Obviously the group names might need changing (suggestions would be good). If you have a look at my user page (http://wiki.spiralknights.com/User:Levonis) I've started to fiddle with how they might be organised to also display rarity, their description, and eventually the monster families/types that drop them. Someone with proper wiki knowledge could definitely do a better job. :P
Good show ol' boy! You've collected more monster drops then I have info on the monsters that drop them! Your organization and icons are of top quality as well, keep up the good work!
