Minstrels who take to the battlefield often are used to directing allies mid-combat, pointing them to the foe to slay.
Decree
This functions as Perform except this is restricted by sound, as your allies must be able to hear you (but they don't need to see you to benefit from this bonus). It is also limited to only one individual at a time (however switching who you're targeting is a free action). When doing this select from; attack, damage, Defense/Avoid, or Mental Defense. You grant a bonus equal to Smarts + Luck on this task.
When gaining Improved Perform you can either select an additional ally to benefit from this when starting or instead grant a +2 to the bonus. For Greater Perform, two allies can be chosen to benefit or the greater bonus can be used which is +4 now instead of +2. And finally, Unleashed Perform allows you to target up to three individuals with this ability or grant a greater bonus of +8.
This alters Perform, Improved Perform, Greater Perform, and Unleashed Perform.
