@JeremyECrawford Priest 12th level casting sacred flame having potent spellcasting (light domain) and 18 wisdom will do 3d8+4 or 3d8+12?

@Lexar131 @JeremyECrawford @ChrisPerkinsDnDcan you please clarify that. If the +wis mod is for all dice’s or just one?
typically just one, unless an effect specifically says otherwise

Potent Spellcasting adds a cleric's Wis. mod. to a cleric cantrip's damage, not to each damage die of the cantrip. https://t.co/4uSrfA47mL
