The hobgoblin player race from "Monsters of the Multiverse" has an ability called Fey Gift which allows you to take the Help action as a bonus action and which reads (in part):
Starting at 3rd level, choose one of the options below each time you take the Help action with this trait:
It then lists 3 options, each of which makes reference to
... the creature you help...
This earlier question addresses the Help action broadly, but this question specifically focuses on how Fey Gift works. For the purposes of this question, I am only concerned with taking the Help action to grant advantage on an attack roll against an enemy, not with granting a creature advantage on an ability check.
The answers to the question I linked suggest that you do not choose an ally to help when taking the Help action to distract an enemy, thus when Fey Gift references "the creature you help," that is an unknowable value until a creature actually attacks your chosen enemy, suddenly becoming "the creature you help." How do the extra benefits of your Fey Gift (the options unlocked at 3rd level) interact with this timing?
For example, assume I am a hobgoblin who is 3rd level, and I use Fey Gift to distract a bandit within 5 feet of me.
Because I am 3rd level, I am able to choose one of Fey Gift's additional options, I choose the option that says:
You and the creature you help each gain a number of temporary hit points equal to 1d6 plus your proficiency bonus.
What is the timing on how these temporary hit points are doled out? Do I gain my temporary hit points immediately, and then when my goliath ally attacks the bandit, the goliath gains the temporary hit points?
If I am unable to choose the helped creature (as the linked question suggests), then there must be a built-in delay for the granting of the benefits. Am I missing something?
