Only with insane min-maxing from abusing ICOGs or Miracle Chaos (apparently Miracle Chaos give -10 to +10) on all equips. The resulting damage increase isn't worth it monetarily.

 

Sorry for the delay. Transposed SW is better than Absolab in terms of total ATT, but loses out a bit on stat. If you have Transposed SW you don't want Absolab. If you don't have it, you should go for Absolab then eventually Arcane Umbra. You could probably make a case for it because of the set effects, but it ultimately depends on your damage increase. In other words, the people that already have Transposed SW should go for Arcane Umbra, while those without it should just go Absolab into Arcane Umbra. It also depends on where you are when it comes to killing bosses. If you can kill Hard Lucid and Hard Will, then you should be working towards Arcane Umbra regardless of current gear. If you're currently on NLotus or NDamien, then Absolab would probably be more up your alley.
