Guild Wars 2

It will only be unlocked at lvl 80. The character in the video is downleveled as seen in the bottom left of the screen. Otherwise it would not have access to basically nothing more than the first three weapon skills.

That’s a level 80 character scaled down for the zone. Elite specializations can ONLY go in the third spec slot, which doesn’t unlock until level 71. So while you don’t have to be 80, you have to be pretty close.

The third spec slot opens at level 71, that doesn’t mean that the elite spec will be available. ANet has already said, elite specs open up at level 80. No sooner.
