So, I've been working on making a new tanking spreadsheet for Nightmare Tide (based off of the one that Primalthirst had for Storm Legion), and it seems that a lot of the base health modifiers are bugged, and are not adding the correct amount of health.

Some are working correctly, such as Guardian Phase/Improved Guardian Phase, Enduring, Armor of Treachery, and Courage of the Bear. But all of gifts (that I tested) that increase base health seem to be adding slightly less health than they should, as are some passives that increase base health (such as Good Health in Bard).

Also, the Bard gift is completely broken and is not increasing base health at all.
