I'm not sure how accurate all of this is since the game isn't even out yet or if this is even post worthy, I'll just blanket spoiler all of it:
I was listening to woodenpotatoes daily countdown on youtube while on the clock when there was mention of bloodstone shards and how it ties to legendaries. value: 200skill points, and you thought elite skills were expensive lol... did a quick google search, found a few wikis with some more info. here's a few links:
during the 2nd bwe i don't remember if this npc was there or not i was too blown away by the game to know what was going on: http://wiki.guildwars2.com/wiki/Miyani
the item mentions: http://wiki.guildwars2.com/wiki/Bloodstone_shard
quick video of some of the skins: http://www.guildwars2guru.com/topic/46254-legendary-weapons-preview-and-crafting-informationpictures-video/
I don't know how much of this was already known but i figure this would entertain some. Anyways, endgame much?
