Guild Wars 2

I know that you can transmutate a Legendary weapon to a white trash weapon and then switch character and use a tranmutation splitter to transfer Legendary between characters, but my question is
- can you do it with a Ascended weapon ?

This works for every weapon/armour in the game. As long as you can transmute it, it will work.

scenario followed by a question:
1) equip legendary, making it soulbound
2) transmute legendary onto white, making it account bound
3) give white legendary to an alt
4) transmutation splitter it
what bound status does the legendary have at this point?

Soulbound to character it’s on
