Guild Wars 2

Do you need to have the Required Disciplines on that character that will be making and/or using that Legendary? For example, on my Elementalist, say I want Bifrost. I have 400 Artificing, but not Chef, can I use one of my other characters that have 400 Chef to make those specific items needed and just mail them to my Elementalist, or do I HAVE to have Chef and Artificing on my Elementalist?

No, you can do it on a different character, the gifts are account bound.

Thank you very much!

Except Bloodstone Shard. This needs to be obtained by the character receiving the Legendary.
