Nether Swap pulls the priority enemy into your team or saves a caught ally, so hold it for the turning point.

Swap interrupts channeling spells and pierces magic immunity, so yank an Enigma or Witch Doctor out of their ultimate.

Wave of Terror shreds armor and grants flying vision, so cast it to scout fog and high ground before committing.

Magic Missile is a reliable point stun, so use it to set up kills and peel for your carry in lane.

Vengeance Aura only helps allies while you are alive, so stay safe to keep the damage buff running.

Play aggressively around swap timing, the initiator playstyle is her strongest identity.
