Drop Rate Of Empyrean Weapons Items

Hello,

I'm planning to low man (1-3 ppl) some NM (Bukhis, Chloris, Briareus, Carabosse, Fistule, ...) for the 3 last stage of Empyrean weapon.
We're very flexible on jobs, and willing to get 2 items on each kill. The 1st one being 100% drop, it's all about getting the 2nd one most of the time.

Wiki is useless to know that because people update drop rate whatever form of TH or !! proc they got.

So i would like some return of experience from people who're used to kill those NM with just TH atma or just thief's TH or just yellow !!

Thx.

!! triggers have no effect on these drops.
Bring a THF for optimal droprate.

Grellow doesn't effect it. I did alot of Briareus and carabosse on thf though. I only have TK for +th and I'd say overall droprate on 2nd one was a good 75% at least.

Been soloing cirein on rdm/thf with th atma and the difference between that and no TH is rather noticable

Pretty sure Empyrean items are only effected by Treasure hunter. Since you can get two(2) without yellow/blue proc.

Ok, i guess we'll just bring a thf or use Dread atma depending of the NM we fight.
Thx for your answers
