What you were expecting to happen, and what actually happened?
A status effect (poison) was applied even though there weren’t 13 green gems on the board.
What are the steps to make it happen again? haven’t tried yet.
Do you have any screenshots or video you want to share with us so we can see the problem? Attach them to your post!
As you can see Sylvanimora was poisoned yet there are only 10 greens gems.
I wonder if his spell was missed in upping to 13? The tooltip for his spell says 13 gems.
