Beginning at 10th level, you can add your Intelligence modifier to one damage roll of any wizard evocation spell you cast.
The wish spell states:
The basic use of this spell is to duplicate any other spell of 8th level or lower. You don't need to meet any requirements in that spell, including costly components. The spell simply takes effect...
Notably, Empowered Evocation only applies when you cast wizard spells, but the chaos bolt spell (XGtE, p. 151) is sorcerer-exclusive.
When you choose this domain at 1st level, you gain proficiency in the Arcana skill, and you gain two cantrips of your choice from the wizard spell list. For you, these cantrips count as cleric cantrips.
However, the wish spell has no such clause.
To avoid an argument about whether you even cast spells duplicated by wish I would like answers to assume that duplicating a spell using wish counts as casting the duplicated spell.
What I am still unsure of is: If a Wizard duplicates a spell with wish, does that spell now count as a Wizard spell?
