Guild Wars 2

Hi,
so i did fractals today and noticed the still mediocre damage from spinal shivers. This wasn’t the first time i saw it hitting for a pretty small number (around 400ish) after the patch. So i tested spinal shivers damage with and without spiteful talisman (tier1 spite trait) against some dredge in dredgehaunt cliffs and it seems to not apply the 50% dmg increase per boon removed if you got the trait for foci.
Is this known and i am late to the party? Would be the bug threat more appropriate? If not be warned in traiding 4s cd vs 150% extra dmg.

Edit: Did some more testing around this. If you use the trait, spiteful talisman, you definately not get the bonus damage per boon removed on spinal shivers.
Chill of death (cast spinal shivers on 25%) however works how it should even with spiteful talisman and also does around 15% more dmg than spinal shivers with 3 boons removed. I did not use close to death for this so i don’t know why it deals around 15% more. Maybe a downscaling issue.
