I just noticed that I incorrectly used who instead of whom in a rec that I wrote for "Arcane Asylum".
Note to self:
To check whether "who" or "whom" is correct, simply substitute the personal pronoun “he/him” or “she/her” for “who/whom.” If he or she would be the correct form, the proper choice is who.” If “him” or “her” would be correct, use “whom.”
