Does the Elemental Adept feat apply to the Wildfire Druid's Enhanced Bond?

Question

So, Enhanced Bond adds a d8 to the damage of a fire spell

Whenever you cast a spell that deals fire damage or restores hit points while your wildfire spirit is summoned, roll a d8, and you gain a bonus to one roll of the spell equal to the number rolled.

And Elemental Adept let's you change a damage die from 1 to 2

Spells you cast ignore resistance to damage of the chosen type. In addition, when you roll damage for a spell you cast that deals damage of that type, you can treat any 1 on a damage die as a 2.

So would the d8 get the 1 to 2 effect with a spell like, say, firebolt?

Answer 1

The bonus to damage from Enhanced Bond is not a damage roll of the spell.

The official wording of Enhanced Bond printed in Tasha's Cauldron of Everything¹ says:

Whenever you cast a spell that deals fire damage or restores hit points while your wildfire spirit is summoned, roll a d8, and you gain a bonus equal to the number rolled to one damage or healing roll of the spell.

Enhanced Bond is a bonus that gets added to one damage roll of the spell, but it is not itself a damage roll of the spell. Since it is not a damage roll of the spell, the roll for Enhanced Bond is not eligible for Elemental Adept, which requires:

you roll damage for a spell you cast

This ruling is further established by the fact that the roll for Enhanced Bond occurs the moment the spell is cast, prior to any attack roll or saving throw occurring, so it is definitely not part of the damage roll, which only occurs after a successful attack roll of failed save (in most cases).
