Immortal serpent

What you were expecting to happen, and what actually happened?
I expect the enemy serpent to die when it has 0 health and to show it’s health consistently.
Instead it shows to have 0 health when I click it but full health in the sidebar

What are the steps to make it happen again?
Beats me. Getting several skull matches at once while also having the serpent dodge might be involved.

**Do you have any screenshots or video you want to share with us so we can see the problem?

Here is the thread on the Agility bug. They expect to have it fixed in the next main patch.
