[RPG] How does the Motivational Speech spell work


Motivational Speech (Acquisitions Incorporated, p. 77) says that you inspire a group of people to greatness.

You address allies, staff, or innocent bystanders to exhort and
inspire them to greatness, whether they have anything to get excited
about or not.

Motivational Speech further grants specified statistical benefits attributed to what inspiration entails:

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.

But is not explicit about what greatness entails. So what does greatness entail? To which greatness are you inspired? Is the greatness chosen by the caster, the DM because it is DM-fiat territory, or by some other circumstance?

Best Answer

I'd say "greatness" is whatever the caster is trying to encourage their targets to accomplish in that moment.

Essentially, the verbal component is you trying to give them a motivational speech for 1 minute, meanwhile weaving in a magical component that consists of the mechanical effects of the spell.

It doesn't involve any element of compulsion, so even though you've given them an inspiring speech encouraging them to do the thing, they could go do something else with the buffs you just put on them. It's just flavor.
