[Bug report gameplay] Zz'rot portal + Relic shield | Zz'rot + Bandit mastery

Hi, I was playing a support game and was running with Eye of Equinox. I had 4 charges and decided to use them ending up smacking a voidling from Zz'rot portal in the head triggering the passive effect but gaining no gold thus effectively wasting the effect. Additionally I have found out that Zz'rot portal voidlings also trigger the Bandit mastery thus giving 1 gold everytime a voidling dies. I do not know if this is intentional as I assume that said voidlings are probably classed as 'minions' thus explaining the interaction with both Relic shield and the Bandit mastery. I also don't see either as gamebreaking but while one is convenient the other awards free gold for the enemy which I think should be fixed.
