My 1st idea is "Tangled Necklaces": You know how they've come up with the Secondary School Mastery Amulets, well I think that you should be able to wear them along with a spell amulet(e.g., I would wear my Balance Mastery Amulet and my Scarecrow's Sinister Vial.)
*(The one I've posted about before)* My 2nd idea is "Link'n Lands(& Castles)": I think we should be able to link our Lands/Castles together, so that we can walk from one to any of the others(like walking across a bridge or something like that), so that we don't have to regrow our plants or worry about picking up all of our housing items(& pets).
So let me know what you think, and keep up the great work KI.
