Hi Nekros, I do not know the system or sheet but is it possible that essence is calculated differently depending on the edition? This is a 2e sheet. I found a formula from 1e online that appears to match what the sheet is doing; code from the sheet; name="attr_Personal_Essence_max" value="@{Essence}*3+@{Willpower}" At any rate, here are the listed sheet authors. "authors": "Brian Shields, Benjamin Bandelow, Matt Zakos, Justin Bradshaw", "roll20userid": "235259, 442, 2861257, 4952661", You might try contacting one of the authors (typically the last listed is often the last person that made sheet edits but YMMV) Cheers
