All shields can be purchased as a buckler instead. Bucklers are 1 weight class lower than a normal shield of their type, have 1 lower ENC, and cost 25% less. Bucklers can not Block (Reaction). Instead, they add an extra degree of success to all successful Parry (Reaction) tests. Additionally, when the defender wins an opposed Parry test they always gain Advantage, but they must pay the AP cost if picking the Special Action Advantage.
