The Armor effect is, as the name suggestions, an Active Effect that modifies the amount of Armor the player has. The effect can either be a buff (positive) or a nerf (negative). In case of buff, the player will receive bonus Armor points which will be taken into account when receiving damage. In case in nerf, the player will experience less Armor points when taking damage. This may result in having less Armor points than the points given from your actual equipment, but not less than zero.
