Blood for Blood:
When activating the node for the zone to follow its initial target, the skill can now be cast on another target than ourself, even though the node to allow other targets than self is not active.
In this situation, the skill should only be castable on self and then follow us for its duration.

Parasite:
When trying to click on an ennemy but clicking on an invoc, Parasite still target the invoc (as most skill do, strangely) and start giving? life (there is no way to know if the invoc gain life but we lose life and there is a visual effect on the skill as we are healing).
It wouldn't be a bug if the node to give life (in skill modificators) was activated. But it is not.
