Guild Wars 2

I made a necromancer speced in spite and when killing a foe i would be healed by the five point trait of spite (parasitic bound) but i dont see any heal or regen or any indication or icon that is missing showing it or did i misread that trait and would gain lifeforce then the traitline should be changed to show it
In the combat lines it doesnt say the trait proced

Confirmed.
Parasitic Bond doesn’t grant health or life force at all.
