How this works
HP, FP, stamina and maximum equip load come from the game's own stat curves for Vigor, Mind and Endurance; discovery from the Arcane curve. Talismans, the Great Rune, Physick tears and buffs apply their effects from the game's effect table: buffs in the same group replace each other, so only the one applied last counts, while talismans and tears stack. Percentages multiply rather than add.
Armour negation multiplies per piece: each piece lets through part of the damage, and the parts multiply. Poise is the sum of your armour's poise; a talisman that cuts the poise damage you take raises your effective poise by the same factor. Roll speed changes at 30% and 70% of maximum equip load. Weapon attack rating uses the same formula as the AR calculator; buffs don't change the menu's attack rating, they change the damage you deal, which the kill-speed simulator covers.
Not modelled yet, so not shown: spell damage itself (spell scaling is shown), and status build-up per hit, which the kill-speed simulator covers. Resistances use the usual stat links (Immunity: Vigor, Robustness: Endurance, Focus: Mind, Vitality: Arcane). More in the methodology.
