Quote:I heard that ethereal dimensional blades can be upgraded via the cube recipe
Only if they're rare or unique.
Quote:The AS states than "ethereal items can be upgraded with this recipe" does it refer to ANY ethereal item, just unique ethereal items, or also regular ethereal items? Can a regular item be upgraded?
It refers to ethereal unique items. Only rares and uniques can be upgraded with the normal-to-exceptional and exceptional-to-elite recipes. Runewords don't count as either.
Edit: slightly inaccurate AND too late. ;-)
You don't know what you're talking about.
