This is a build Idea i will definately test on Tuesday. Theoretically if everything hits at least once (in a perfect world) it can remove 7 Boons and can additionally convert at least 15 Boons into Conditions. If your enemy does not use Boons, it is quite useless, but on the other Hand if your Enemy uses Lock On, your PU Mesmer or Stealth Thief is pretty much useless aswell so everything has it’s downsides :-).
kitten Edit: Totally forgot about Corrupt Boon lol
Could also swap Sig of spite for locust if u want more frequent(and aoe) boon conversion since traited it’ll have a 24sec CD. Also it should heal for around 1200 per target baseline after patch assuming the 20%increase siphon baseline affects it since the trait currently in-game does.
