@Diablo threw a combo-breaker into the endless hashtag promo stuff, and replied to actual game info questions Wednesday evening. This post quotes the interesting stuff about item colors, attributes, and more.
Are legendary items still purple? Oh come on bring back golden items, like it was in previous 2 games… Rare items can be purple..—SpykeKillah
What were the core attributes in D3 again? I seem to have forgotten…—AcidReign87
Why isn’t Willpower called Energy?—Grug16
It’s a bit more flavorful.—Diablo
Will gems function differently according to what type of item you put them in?—MultiKillGaming
Yes. Weapon/Helm/Everything else.—Diablo
We don’t have the final list of socketed items in D3, but we know at least six item types that will have holes. Weapons and shields, plus body armor and helms for sure. Belts and boots were said to be socketed previously, and some other armor types are also possibilities.
Sure are a lot of changes in item colors from D2 (but not so many from WoW). Check the items article in the wiki for the full list. Set items, not mentioned in the tweet, are green. Crafted items are blue/yellow/orange/green, depending on the output of the recipe. There are no plain socketed items as there were in D2, since sockets are granted/treated like magical modifiers in D3.
Personally, I’ll miss golden unique items. The name change to legendary is pointless, but I can overlook that. But the color! First all, just the word, “golden” is an adjective that means “awesome.” What does “orange” mean, other than a word that nothing rhymes with? Why didn’t they change Rares to orange? No one gave a damn what color they were anyway. Or pink, or plaid, or whatever, if yellow/gold were too similar? This should be the real color controversy. I want back that classic golden hue we’ve all been trained to covet.
