Elemental damage

Almost every counter in this game is soft. The damage matrix nudges a matchup up or down, armour shaves a slice off, and a bad composition still trades — just badly. Elements are the exception. They are the one axis where a matchup can become absolute: an immune unit takes literally nothing from that element, no matter how much damage you stack behind it.

Elements are a separate axis from attack and armour type. A fireball is Spell damage on the matrix and Fire on the elemental axis, and the two are resolved independently. A unit can be resistant to spells and weak to fire at the same time.

Weakness raises incoming damage of one element by 50%. There is only one grade — every weakness is the same size. It affects damage only: a fire-weak unit is not easier to chill, poison or shock.

Resistance lowers it, in three grades: 25%, 50% or 75%. Grades never stack — a unit carrying two of the same element uses the strongest. Resistance also blocks that element's status effect outright, at every grade, so even the cheapest tier stops the chill or the poison entirely.

Immunity removes the element completely — zero damage, and no status from it either. Immunity outranks everything else, and all seven elements have one — Shadow and Acid included.

Weakness and resistance are independent, so a unit holding both simply multiplies them together. All of it lands before armour, so armour still applies on top.
