Die so fast

I am an Elem. lvl 20 , I play party 4v4 , some time I get killed immediatly , from full health to death !

Is there a skill that can do this ?

Fragility build? Most likely a Mesmer's trick.

Or a necro trick.

To the OP: you need to keep an eye on any hexes or other effects cast on you. Also, don't stay around if an area spell (firestorm, well of suffering, whatever) is cast on you.

maybe your armor suck.. :/

Immediately?...as in...

1 spell BAM you're dead?

or "immediately" as in...~5 seconds?

May I ask you where you play? EU or USA?

There is no one skill that will immediately kill you, but there are several combinations of skills that can bring you down from ~500 life to dead in around 6 seconds; sometimes faster if you try to cast a spell. Most of these spells are hexes, and you will notice them in the upper left corner of your monitor.

Good luck,

probably a fragility build, they seem to be the ftm

Fragility build. And yet somehow this build surivies unscathed. It is basically a one shot kill. Once fragility lands on you, you are a dead man walking. If you are lucky enough to have a hex removal more than likely you will not cast it before you are dead.

Why Anet did not adjust this build baffles me.

because the only build people whined about was NR.
