Please help me solve a mystery!

[Arkat]

Below is a combined screenshot of the Hit Point totals (and the categories that contribute to their total) of my two Melee monks.





What I want to know is, what exactly the "Enchanted Bonus" is supposed to reflect?

I know that Hit Points due to Vitality, False Life, Insightful False Life, Quality False Life, and Profane Lifeforce all contribute. Hit Points due to spending Reaper points may also be included here, but I am not 100% sure about that.

Arkat has a +50 False Life item (armor) and a +20 Vitality augment.

Mirano has a +54 False Life augment, a +44 Vitality item, and a +12 Quality False Life item.

But, clearly, there are other things that contribute to the "Enchanted Bonus." I just don't know what they are.


Just for completeness, the rest of the categories are pretty self-explanatory.

The "Base" is the Hit Die type (for Monks it's 8) per level (so 160 HPs) plus the number of Epic and Legendary levels times 10 (so 120 HPs) for a total of 280 HPs.

The "Feat Bonus" includes the various Toughness feats, the Favor Reward feats, Heroic Durability and Improved Heroic Durability feats, and probably any hit points gained from APs spent in the Enhancement trees and DPs spent in the Epic Destiny trees

The "Fate Point Bonus" comes from when you see the Fatespinner and she sends you through the portal to unlock the various Epic Destiny trees.

The "Percentage Boost" comes from the various hit point scalars. You can see what your "Max Hit Point Scalar" number is by looking in the General Combat category on your Character Sheet. Mirano's scalar is +145%. Arkat's is +135%. The difference between Mirano and Arkat is Mirano wears a 4-piece Emminence of Winter set which adds a +10% more Hit Points. Arkat does not wear such a set, although I am considering a gearset that adds that.

Thanks for any help.
