Guild Wars 2

Just a question, how do i remove the electricity from the room when the whole room is electrified? Standing on the panels dont seem to work :/

Use the holographic NPC!

Thats not working either :/
Do i kill it on the raised ones or the down ones? Because killing them on the raised one does not make it go down….

Have to kill the holographic pirate near the boss so it explodes on it
