All Mog House GP Items

So today i just bought the stone hearth and i all ready have the stall for +5 smithing skill and did not receive a higher ki. so what im asking is do the 150k, 200k and 50k GP items matter since u can only get 1 ki active in mog house making the stall > everything else combined? Or do they stack making it +5 stall +3 other GP moghouse items +3 adv image support +4 from gear = +15


inb4 3hit smithing build blah blah blah

greatly apreciated for clearing this up ty everyone

stall over takes all other house items so in other words unless u like to make ur house look nice u wasted alot of time sry.

3hit smithing build lolol

I'm not sure how other crafts work, but if they made it anything like fishing there is a difference. But don't get excited, it's not skill. For fishing, once I got all of the fishing guild point items I could reel in a Matsya legitimately, without getting the message "you don't know how much longer you can hold this" whereas before I got the last KI it would show up 5-10 seconds earlier. So I'm guessing it doesn't help your skill but you might lose less synth materials or something of that sort.
