Can the following two mechanics work together or are they mutually exclusive or require something else? I am the DM. Both the player at my table and I don't agree or understand if it's possible to utilize Enthralling Performance in conjunction with the spell motivational speech.
Enthralling Performance (Glamour Bard ability)
Starting at 3rd level, you can charge your performance with seductive, fey magic.
If you perform for at least 1 minute, you can attempt to inspire wonder in your audience by singing, reciting a poem, or dancing. 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 speaks to it, and it hinders anyone who opposes you, avoiding 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.
Motivational Speech (Acquistions Incorporated, p.77)
Casting Time: 1 minute
Range: 60 feet
Duration: 1 hour
You address allies, staff, or innocent bystanders to exhort and inspire them to greatness, whether they have anything to get excited about or not. Choose up to five creatures within range that can hear you. For the duration, each affected creature gains 5 temporary hit points and has advantage on Wisdom saving throws. If an affected creature is hit by an attack, it has advantage on the next attack roll it makes. Once an affected creature loses the temporary hit points granted by this spell, the spell ends for that creature.
Does using one of these preclude using the other at the same time?
