uh about leveling I dont think 'HOW MANY' items + 'HOW MANY' items will increase but seed + muck or small wooden gear + small wooden gear is the best one to use ...

small wooden gear if you're not a collector it cost buying lauan but muck and seed are free ... RANK 1 items + RANK 1 items is the best

most people use muck and seed but either way try them both

regarding the "+" i think so it is how rare its going to be but sadly my friend i am sorry if i cant answer what is the "-" version of the plus thinggy

hope ive help even a little
