[2019] In what ways are Wandering Spirits minions, and in what ways are they not?

Wandering Spirits are not minions, but there are two ways in which they’re similar to minions:

1. Casting Wandering Spirits counts as using a minion skill.

2. Wandering Spirits’ damage is affected by “increased minion damage”, and other such minion damage modifiers.

I’ll amend the tooltip in game to make this clearer.
