AS topic states, where can i farm for aether crystals ?
portal your way to hidden laboratory and run backwards going to the bloody shrine in the underground transit… you will reap tons of them…
or if want more fun try port valbury until the end boss:rolleyes:
Hidden lab won’t drop 'em at 45. Below — possibly.
At 45 I’d run Conflagration, or two clusters near Asterkarn Valley rift, if you find Conflagration somewhat scary. Or Cronley runs, as “+” you’ll get to farm his ring, and clusters there are always scaled up to your level, even when other area is not. As “-” — it’s the longest route by far 
I’ve gotten crystals off the hidden laboratory run up to level 42, but I’m pretty sure they don’t drop after that.
The conflagration is a gut check on HC, but yields pretty good crystal and shards well into your 50s. The quarry is not far from the rift gate above Blood Grove and has crystal, dynamite, and a relatively easy boss. The quarry doesn’t make you run as far over Aetherfire ground to fetch crystals.
The aetherial rift in the conflagration is doable around 45, but the mobs are more nasty for only a moderate amount of crystal.
I recommend doing several crystal runs at the hidden laboratory rift mentioned earlier in the post prior to level 42. The room in front of the Warden’s office has at least 4 crystals and might even drop them after level 42.
I usually just farm the aether clusters to the right of the Arkovian Foothills rift. Clear, loot and restart session.

You need to go to elite now to farm crystals. You are too high level so they won’t drop. You can maybe try Valbury. Not sure
As superfluff said, you should reach elite and there you’ll be able to farm warden lab for a good amount of aether crystals/shards per run (usually a dozen)
Are you sure?
I thought crystals farming is only doable in ultimate :undecided:
Port Valbury Outskirts (no key needed) on Veteran is where my level 43 bm got most of his crystals from, so I can see no reason to not be able to farm them in any difficulty :undecided:
