The description of the [*spirit shroud*](https://www.dndbeyond.com/spells/spirit-shroud) spell says (emphasis mine):

> **any** attack you make deals 1d8 extra damage when you hit a creature within 10 feet of you.

The description of the [*green-flame blade*](https://www.dndbeyond.com/spells/green-flame-blade) spell says (emphasis mine):

> On a hit, the target suffers the weapon attack’s normal effects, **and you can** cause green fire to leap from the target to a different creature of your choice that you can see within 5 feet of it.

To me, that sounds like the single attack from *green-flame blade* is damaging 2 creatures, and the extra damage from *spirit shroud* should apply to both creatures.

**Does the target of the secondary damage of *green-flame blade* also receive the extra damage from *spirit shroud*?**
