Empyreal Fragments?
Ascalon shall be reborn in us!
Jumping puzzles. A few of them are very easy like the one in Eastern LA, the cave in Queensdale and the one in the zone north of the Citadel.
Dungeons. You can pick a set of armor or needed tokens for legendary and grind out both frags and the tokens at the same time
WvW. Go kill that other server!
Are the fragments in WvW rewarded for caps or player kills?
Ascalon shall be reborn in us!
They are for killing the supervisor at the camps. You need not need to cap the camp but you do need to do enough damage to get credit for loot.
There are quite a few easy JPs.
Right now you can also buy Wintersday Gifts to get all 3 types of the ascended crafting materials along with the quartz crystals.
