Guild Wars 2

Bloodthirst does not affect Vampiric Master, minions siphon 79 per hit whether you have Bloodthirst or not. Is this a known bug or working as intended?

Healing power and/or condition damage also have no effect on siphon. So like what you mentioned it seems like a bug, but Anet has not officially acknowledged this, so there is a good chance it is working as intended.

A comparison for this would be bleeds caused by clones/minions. They do not benefit from your characters condition durations. Since the siphon is actually coming from the minion, who does not have the improved siphon trait, it would be logical that it would not be improved.

That’s disappointing, even with 5 minions 79HP per hit isn’t anything to shout about, especially for a Master trait. Oh well.
