if included ur both main and 2nd weapon is only +7 or +8, then i suggest u remain ur 5 set of apo armor, then change ur 2 weapon to lv50 blue, a +10 lv50 blue weapon is much higher atk/matk than a +8 lv40 epic..

and if u wan to say enough, sure full set apo +7/+8 is enough, juz that u may take 1 hour to finish 1 dungeon abyss run with such eq... now ppl mostly remain 5 part of apo/manti set to get the set bonus while change the 2 weapon to lv 50 blue to max out the dmg 1st before they slowly change to totem/immortal set... it helps alot...

Depends on the abyss dun your running, some might only take 20-30 mins.. others well, 1 hour + lol.

you can safely npc those reverts or keep as souvenir....lol
now it doesn't need to use revert to change potential already...just reapply the Agate/Crystal code to replace the current potential 

Cannot get coupon for now, it has been remove from the box.

If I remember correctly, Set accessories like HT/Dangerous Desire is from hell mode dungeon ending (the chest was it?) (or the chest selection screen) and Great Ancestor has a small % chance to get it from the chest selection screen in the hell mode dungeon (60), Materials (Fragments) for skills are from Chaos Opening, craft them at Blacksmith in the cities/town (Accessories tab) (Stats for the ring (except the skills) obtain from crafting the ring are random).

PS:You need the rings (normal, 60) together with the fragments to craft the ring, the rings (normal) can be get from ladder pouches and Hell mode dungeons (I think? can't remember sorry).

IIRC, they drop from dark lair (Hatred Pesadelo) (and higher levels)

Accessories set (Ring/Necklace/Earring) of Hon Tribe/Dangerous/Twisted cannot be craft. Only can be obtain by clearing lvl 60 Hell Mode Nest by low %.
If you're talking about skill accessories(not set), those lvl 60 epic will definitely drop from lvl 60 hell mode nest.
Then you need lot of Fragment of Giltter/Subtle skill materials (Can be obtain from Chaos Opening aka Rabbit Portal)
Once u have both epic accessories(not set) + fragment skill, go to Berlin NPC and craft your desire skill accessories with "Random Stat".
Drink it and try..
Origins have several effect time, jz read the description.
