I've been checking out the Hunt Registry/Evoliths system in case the upcoming updates utilize more of its true potential.  I noticed that there was a lot of info, but there is no breakdown of the Evoliths by their rarity or difficulty to obtain.  And so here I've sorted the current list of Evoliths using info provided by FFXIclopedia.  It's interesting to see which types require the most Scylds as an indication of which Square seems to believe are the best available.  Since the purpose is to see which Evoliths may be "better" this list doesn't include Evoliths from any NM's that require 0 Scylds to hunt.  Here's how it goes:

It's interesting to note that the 5 HNM fomors who wield Aern-like weapons also all grant "Vs. Luminian" stats.  And the pathetic -1 minute 2 hour delay Evoliths cost 40 points which is a joke.  Hopefully there will be better and more useful Pigments and Evoliths available soon.  Right now there are a few niche combinations that might be useful but considering the cost and time spent are of arguable worth.  I've been taking Shamaya's advice and spamming Goblin Wolfman to store up a few easy Scylds.  If you're bored and wanted to try to make a little money Habetrot could also work.
