@WellPlay that Eternal Divination is Legit, Eternal Items have a chance for their Epic Affixes to be Crystal Affixes, if the Affix is on the Crystal Affix List.
@MATANDA the first and third Eternal Divination are Legit, Eternal items can have Crystal affixes if the Epic affix is on the Crystal affix list.
the second Eternal Divination you posted, the one with Skulldraga on it, I just tested it, and if you take an Eternal Divination and use Jasper on it to change it to Warrior and then back to Wizard, the Torrent will change to Skulldraga. Wizard to Rogue to Wizard it stays Torrent, but when I went Wizard to Rogue to Warrior to Wizard it goes Torrent > Sentry > Torrent > Skulldraga. so that is also Legit.
here is a post that lists the possible Crystal Affixes:
also, when using Jasper Crystal to change an Item from one Class to another, both Talents and Skills will change. Items like Divination (Wizard item with Warrior Skill), when I switched it to Rogue, it kept the Torrent Skill, and because Torrent is Warrior Skill, when I switched it directly back to Wizard, it stayed Torrent. so there are special situations for some items.
I haven’t seen a list of conversions of Talents and Skills from one Class to another, but I believe the conversion isn’t random, so with some testing you can find out which conversions are beneficial to your builds. there is a Warrior item that has a Skill that when I use Jasper, I got Mana Shield on my Wizards Bracer, even though I did it for the Crystal Block!
here is a post of which Crystals can & can’t be used on Eternal items.
here is another post that shows affixes that can only be found on items and can’t be rolled with Crystals.
also, I think Extra Attack Chance can also be found on the Living Force Ring & Necklace items of all Classes, even though it is usually only found or rolled onto Weapons.
Block can be rolled on OH items only of any Class, but can be found on a few other Warrior items except for the Neck item. you can try looking for posts of which items have Block or just look in the Codex > LegendEx > Warrior.
