Guild Wars 2

so i have made twilight the old way about 2 months ago, now i want to get sunrise
so am planing to create it using the new legendary system, so i have decide to make sunrise
then make eternity sell it and keep both twilight and sunrise skins

my Q is, will eternity be even sell-able after using the sunrise that i made using the new collection way or will i wont be able to sell due not being able to sell the collection legionaries ?

It should still be sellable via TP because the toilet technically destroys the 2 legendaries you put in and creates a brand new item. In that sense The Eternity crafted by your method in comparison to the “old” way would be no different.

The collections make the precursor for that legendary. From that point on, you still use the old system.

Eternity is always sellable if made in the forge from one twilight and one sunrise (regardless of whether either is bound). This is why Eternity is so ‘cheap’ relative to the other two greatswords.
