I know this is an old thread, but it's the only one that I could find with my current problem.
I'm playing against a mate in the <PvP Duel> option, where we both are playing with Darkness as main element.
I've casted Liquid Shadow on a Minor Vampire of his twice, divided on two games, where the poison only made one dmg each time.
First game I thought I'd missed something out since it didn't die.
Second game I looked for the same behaviour and it happened again. I mouseovered it and saw the health resat to full and back to 1.
After a few turns I casted Nightfall to see if it would restart the poison - no effect and the Minor Vampire was still on 3/2
From what I could see, then the coding of the vampire makes it reset health pool when it's affected by Liquid Shadow. It would be interesting to see if a deduction in power would reset as well.
I hope this can help out the card designers/coders to fix this "old" bug ???
Cheers
