when the next expansion is released yes but until then you gotta buy boxes with owls or trade for them
Uh...no, he is asking about LEGs, not EXOs. As it stands, LEGs cannot be forged or sacrificed in the forge. They're only accessible through that 5% chance of getting a LEG from a pack. This might change, but it might not.
my mistake legs are still acquirable through buying boxes none-the-less the only difference from my earlier post is they wont be available to forge
