Morde/Blood Lord Vladimir visual interaction Pictures.

Using Blood Lord Vladimir and being healed from Mordekaisers W while Vlad is inside of the minion wave will create a black mass around him (this is visual to all players in the game) This happens every time if Vladimir is nearby an enemy minion or jungle monster (excluding skuttle).

I assume this is due to Vladimirs Q animation thinking it needs to go off since vlad is healed however since the spell wasn't cast it just defaulted to black.
