I think it would be nice to have a transmuter allowing the player to summon only one wind devil, but it lives forever.
If you did that, I’d probably say also make it’s damage scale as if you had 2 of them out. Because even at default CDR, that is a large dps loss in losing a WD, and losing out on the fact the second WD can proc devotions for you. You effectively would be trading the pain of clicking the button every 5 seconds for a WD with less than half the overall power of just clicking every 5 seconds.
Yes but maybe you don’t care about the damage. The slowness, resistance reduction and impaired aim are good enough.
They run away from shit I want them to attack anyway, so…
There is a pet attack command 
I don’t think they count as pets?
It still works for them. Same thing with Mortar Trap and Blade Spirit.
I like this idea a lot. Get tired of having to constantly summon these things.
