The Lich’s skill Death Seal can limit your HP to 33% of the whole HP globe. That makes changes to that little tanky HP pool tricky to see.
Suggestion: Instead of capping the HP at the bottom third of the globe you could only display the left third of the globe (with a well visible border btween the HP fluid and the empty remaining 67% of the globe).
→ The user would still see that Death seal is capping the HP pool, but could see changes to his/her HP better.
