Guild Wars 2

When I begin the fight, I use Stand Your Ground and attack. I immediately get knocked back and slapped around by tornadoes. I finally get up and cast Hallowed Ground. Without ever taking a step, however, a tornado knocks me out. I should have stability this whole time.

Is there something I’m missing?

I’ve had a few instances where my 6 second invulnerability skill didn’t seem to work (signet of stone). I would use it, but still take damage from a few bosses. Seems like some of these bosses don’t follow the rules.
