What you were expecting to happen, and what actually happened?
I expected devour wouldn’t work since elemaugrim is immune
GW battle. Pretty sure it was his first cast. I did battle via the combat log so I could screenshot the matchup. No way elemaugrim should have been devoured. Kraken definitely had his stats after.
What are the steps to make it happen again?
