Stepped proportional value modifiers

Situational modifiers are applied as discrete proportional steps to a unit attribute (e.g. +50% / -50% of its base value, capped and cancelling one-for-one) rather than as additive adjustments to a die roll.

Increases and DecreasesTercios: Brevis Editio

Situational modifiers scale a unit's attribute values in half-value steps instead of adding to die rolls.

How it works

Each Increase adds half the original value (rounded down) and each Decrease subtracts half; Increases and Decreases cancel one-for-one. Two or more net Increases cap at double the original value; two or more net Decreases set the value to 1. Since most values are dice counts (Speed, Melee, Shoot, Discipline, Courage), orders, terrain and Weariness change how many dice are rolled or how far a unit moves.

Increased Value: The Value will be increased by half of its original value, rounded down.
