Talents hold the specialised options omitted from the core rules, from combat techniques to Shaping itself. Pay the listed Improvement Point cost once and record the Talent. Skill and Characteristic prerequisites must be met when it is bought; listed equipment is a use requirement, not something that must be held during purchase.
Passive Talents apply whenever their conditions are met. An action Talent spends the Combat Action; a reaction Talent spends the Reaction named in its text. Only one action Talent can modify an attack, and an attack made by an action Talent is not a standard attack for extra off-hand attacks. Passive Talents still apply when relevant.
When a Talent forfeits all Reactions, that includes the base Reaction and every extra Reaction. A declared Talent replaces normal attack damage or critical effects wherever its text says so.
When a Talent works only if its hit is not stopped, use the combat result matrix. On an ordinary hit, a successful Dodge or a Parry that would block all damage stops the Talent; a partial or ineffective Parry does not. A critical Talent hit is stopped only by a critical Reaction. If the Talent deals damage, apply any partial Parry before armour.
