Guild Wars 2

So I’ve died 10 times now and utterly fail to see how to do this.

I get to the repeat of the second phase and for the life of me I can’t get more than 3 of the 4 fires lit!

I get the 3rd and then there’s no Fire up and by the time I get to it at least one of the 3 already lit has gone out.

Like I say I’ve fied 10 times, raised myself (using pet) only to fail again.

It seems impossible when the Fire circle takes so long to respawn after using it.

Is there ANY way to do this solo?

Smothering Shadows will spawn after each quarter of the ring is lit – each time you light a quarter, it will spawn a single Smothering Shadow.
You can kill Smothering Shadows by being lit by divine fire and attacking them – killing them, however, will remove the buff forcing you to get it again before you can light the next portion of the ring.
The best way to counter that is to remain standing in the ring Rox creates and range the Smothering Shadows down as you will be immediately re-buffed.
