Pact of the Chord

You can use your actrion to create a pact instrument in your empty hand. You gain proficiency with this instrument while holding it. While you have proficiency with a given pact instrument, you can add your proficiency bonus to any ability checks you make to play music with the instrument.Your pact instrument disappears if it is more than 5 feet away from you for 1 minute of more. It also disappears if you use this feature again or if you dismiss the instrument (no action required).

You can transform one magic instrument into your pact instrument by performing a special ritual while you hold the instrument. This takes 1 hours and can be done during a short rest. You can then dismiss the instrument, shunting it into an extradimensional space, and it appears whenever you create your pacts weapon thereafter. The instrument ceases being your pact weapon if you die, if you perform the 1-hour ritual on a different instrument, or if you use a 1-hour ritual to break your bond to it. The weapon appears at your feet if in the extradimensional space when the bond breaks.

Invocations

Misty Song (Pact of the Chord)

While you are playing your pact instrument, you can create harmless, illusory visual effects within a 15-foot-radius sphere centered on the instrument. Sample visual effects include luminous musical notes, a spectral dancer, butterflies, and gently falling snow. The magical effects have neither substance nor sound, and they are obviously illusory. The effects end when you stop playing.

Improved Pact Instrument (Pact of the Chord, Level 5)

You gain a +1 bonus to spell attack rolls and to the saving throw DCs of your warlock spells. You can use your pact instrument as a spellcasting focus, substituting it for any material component that does not list a cost.

Enthralling Performance (Pact of the Chord, Archfey Patron)

If you perform for at least 1 minute using your pact instrument, you can attempt to inspire wonder in your audience. At the end of the performance, choose a number of humanoids within 60 feet of you who watched and listened to all of it, up to a number equal to your Charisma modifier (minimum of one). Each target must succeed on a Wisdom saving throw against your spell save DC or be charmed by you. While charmed in this way, the target idolizes you, it speaks glowingly of you to anyone who talks to it, and it hinders anyone who opposes you, although it avoids violence unless it was already inclined to fight on your behalf. This effect ends on a target after 1 hour, if it takes any damage, if you attack it, or if it witnesses you attacking or damaging any of its allies. If a target succeeds on its saving throw, the target has no hint that you tried to charm it. Once you use this feature, you can't use it again until you finish a short or long rest.
