I currently have a 57 vitality and yet 730 max health. Account is Gambit on beta server. While it seems to be linked to a new helm I purchased I am unsure. Testing things by removing items containing vitality can lead to a lot of wasted regeneration of hit points.
I have several items with vitality on them but none with extra health. So I can't explain the total. This is not the first time this has happened to me. I once removed an item with 4 vitality and sold it later finding out I lost 140 health - not forty. I have also seen my dexterity incorrect in the past. Each of those times I have had quite a few items improving the attribute that seemed to be affected.
My question is: Is there some dynamic/rule that I am unaware of outside of class that affects realized attribute totals?
Gambit
You have 57 vitality from attribute points - 5 vitality base - 52 vitality - 520 health
+ you start with 100 base vitality - so in total 620 health.
Now, as I can see, you purchase a vitality + 11 helm which should give you additional 110 = the 730 health which you have.
The problem seems to me that it doesnt seem to add the 11 vitality from that helmet to the total number of vitality attribute points. Its probably a visualization problem as it seems to account for its presence in your total health
