WeakAuras - Shield Barrier Icon?

[Sevyvia]

Heya.

Relatively minor question, but it's annoying me. I can't find the shield barrier icon when I try to choose the icon myself, and leaving it to try and detect the icon itself simply shows a green square. Does anyone know what the name of the icon is, so I can calm down my raging mental disorders? :P

You already got your answer, but another useful thing to add is that you can click icons on wowhead to find their names.
