If it's a set item however, you can convert it to another piece of the same set with the cube (doesn't work for sets with only 2 items). Reforging will only re-roll the stats on an item but keep the base item the same.
Ethereals only drop in Seasonal play, and will not transfer to your non-seasonal character when the season ends.I may be a bit confused by your question, but if you're missing items reforging won't help you. Players who accomplish this will have all Ethereal transmogrify options available for future seasonal and non-seasonal play. Collecting all 21 Ethereals during Season 24 will reward players with the Feat of Strength, Ethereal Recollection. Ethereals cannot be Enchanted, Transmogrified, Dyed, Reforged, or traded. Legendary Powers and Class Passive Skills rolled on Ethereals do not stack with the same power equipped through Kanai’s Cube, Items or Skills. Only one Ethereal can be equipped at a time. Each Ethereal has fixed affixes and rolls one random Legendary Weapon power and one random Class Passive Skill. There are 3 unique Ethereals per class. Ethereal rarity drop rate is set between Ancient and Primal items. Ethereals cannot be acquired through Kanai’s Cube or from Kadala. Ethereals are account bound and can only be dropped by monsters, chests, and destructibles, but do not require your character to be level 70 to drop. For additional details on Ethereals, check out the list below:
Ethereals will have unique icons, names, item types, and sounds originally found in Diablo II. Ethereals will roll a powerful set of affixes, a random Class Weapon Legendary Power and a random Class Passive Power. Season 24 introduces Ethereals, a new weapon-type that players will be able to acquire and hunt for in their upcoming seasonal journey.
Can I reforge ethereal weapon? Will it change to non ethereal?
