Ja, för att utlösaren var minion som gjorde en attack som inte inkluderar dig. Huruvida den attacken saknar spelar ingen roll. Minion måste missas av en attack som behandlar skador på en miss för att den ska ignorera den skada.
Monster Manual, page 282
A minion is destroyed when it takes any amount of damage. Damage from an attack or from a source that doesn't require an attack roll (such as the paladin's divine challenge or the fighter's cleave) also destroys a minion. However, if a minion is missed by an attack that normally deals damage on a miss, it takes no damage.
