The Magic Pet Mirror might be getting some updates in the expansion! I say "might" because all of this could change; nothing is set in stone.
Currently on live servers the Magic Pet Mirror costume disappears when you do ANYTHING other than emote. Need to hearth? Say bye-bye to your buff. Summon a different pet? Nope, can't do that. Cast a spell? Sorry, can't do that without losing the costume either.
But good news everybody! In Legion you can do all of that and more! *throws confetti* :D
After doing some testing, it looks like the following will work with the Magic Pet Mirror:
- most player spells can be cast
- logging in and out
- summoning another pet
- mounting (will temporarily remove the costume, but you retain the buff and regain the costume after dismounting)
Entering combat will still remove the costume.
Most player abilities can be used, but there seem to be a few that will yank you out of pet-form. Shadow Priest Psychic Scream for example. There are probably others that still don't work with the mirror buff, but I haven't been able to test everything.
A few fun combinations:
- Druids retain the costume while shapeshifting (minus travel form)
- Fishing while a pet
- Paladin bubbles + pet costume
- Hunter Feign Death + pet costume (it's a bit sad-looking though...)
- Priest Levitate + pet costume
Magic Pet Mirror + Mage Mirror Image causes your images to turn into whatever pet you copied. If you enter combat, you lose the costume, but your images don't!

There are so many more awesome combos, I'm sure, but since I don't have time to try them all out we'll just have to wait and see what creative things players come up with once Legion goes live. ;)
And just for fun, rogue kitty! When claws just don't cut it anymore hehe.
