Non-pet non-combat pets (character based environmental effects)

Athyrium93

I was looking though the crown furnishing shop, just window shopping and checking out what was new, and had a crazy idea while looking at the environmental effects. How cool would it be to have them as a "pets" to be able to have a swarm of butterflies around you, or be surrounded by fog, or little twinkling lights.
There are already sets that do similar things, but they don't fit every build and some of the coolest effects are on bad sets (looking at you, grace of gloom)
I'd spend a silly amount of money for something like that.

They kind of dipped into that when they released the Ancestor Moth Swarm "pet." Seeing more stuff like that could be fun.
