So....demon gate...

It jumps off the face of the earth when my group and I use wall or anything with knock back abilities....we've died cou.tless times to this because then the whole map gets covered by the massive aoe that it does(hits everythin besides what is directly in front of it).....Its easy to say its annoying in the least.....also other bosses do it too since the whole adding of the door. I lost an orb because I thought I could somehow glitch it back)

 

....Try contacting support?
