Death Bulwark Boon

finwe29

I just got my third Master Boon and in the beginning I had chosen Death Bulwark. The third rank of that give a change to get temporary hit points when an enemy is killed. However, I am a wizard with the power to get a shield as temporary hit points. But when I now kill a creature and the boon is activated, my shield disappears and I get a lot less temporary hit points. I have been in contact with Arc Games Support and they said that it was most likely a bug and that I should report that here.
Thank you
