Guild Wars 2

So it seems Signet of Vampirism can’t be dodged, can’t be line of sighted, and corrupts at near infinite range. Evidence of the latter shown here: https://youtu.be/B3n4hFowCvo?t=21

Also no invul/block helps.

I think you cant only prevent it with “facing”, as it cant fire backwards.

It has always been that way. SoV counts as a Mark skill which doesn’t do anything to the target itself except marking the target with 25 stacks of Debuff, and unaffected by block, evade, invul and even blind but you have to face the target. But due to the GM trait, Signets of Suffering, it turns SoV into an unavoidable corruption. It is that good but this is a healing skill with 1.25 cast time at 35sec CD and barely heal you for 3960hp. It is an offensive Healing skill. If you nuke a necro, SoV will likely not save him at all.
