Guild Wars 2

Ok so i’ve seen a few discussions about similar things but can’t find one with my situation and i’d much rather be safe than sorry so i’ll ask myself.

I have Zojja’s coat on my norn thief but I just made a human thief (norn too big) and I want to keep the stats and look of the ascended coat but transfer it to my new human thief, how can this be done?

No garantie that it works, but a guildmate said he did it with an ascended weapon:

You should be able to transmute that armor piece onto a white/blue armor piece to make it account-bound. Then shift it to your new thief and use a transmutation splitter to get the original ascended and white/blue armor piece back, making the ascended soulbound to the new character.

On a similiar theme.
I have some dungeon armor piece i have transmuted this ascended stats.
If i use a splitter on those would the dungeon armor revert back to exotic stats and the ascended armor back to its original status before i transmuted them. Also would both pieces stay soulbound to that character?
Hope i have worded this corretly

Yes if you use the splitter, you will get the original nice looking exotic dungeon armor und the “however you think it looks” ascended armor piece.
I think they will still be soulbound since I can’t see a reason how it could change, since the only way to change soulbound, is to use the transmutation “trick” to make it account-bound, but you did not do that.
