Gloaming Smite gives the following combat text when used:
"you whisper a prayer to the Trickster before slipping into the shadows and stalking towards the Lupine Archer. [hitMiss|[attacker.CombatName] lunge[tps|s] out with a gloam-edged strike, leaving [target.combatNames] head engulfed in cloying shadows! (-136) Critical Hit!|If [target.combatName] ever notice[tps|s] the strike that comes from the shadows, narrowly missing [target.combatHimHer], it's hard to say."
It also does not give Obscurement to the Champion.
