Guild Wars 2

The wiki says:
“Ascended chests are a special kind of container that drop from Fractals of the Mists, Guild missions, exotic champion loot bags and WvW Rank chests.”

but i also remember reading somewhere that everything that drops ascended mats, have a chance to drop a chest too.

What are the possible ways to get an ascended chest?

According to patch notes: ‘Ascended weapons can now drop anywhere ascended materials or other ascended items can be found.’

So, that would mean the weapons can drop from:

Open world bosses, temple bosses, WvW keeps, and castles now drop Dragonite Ore in addition to their regular loot, which can only be earned once per day per location.

Dungeons, minidungeons, jumping puzzles, WvW camps, and towers now drop Empyreal Fragments in addition to their regular loot, which can only be earned once per day per location.

Liquid Karma dropped from dungeon end chests have been replaced with Empyreal Fragments.

This would be all the places, according to the patch notes, as well as what the wiki says (though I don’t know what the wiki uses for their source).

I think they are in the same place as the RL unicorns.

perfect thats exactly what i was looking for, thank you.
