Blade Spirit/Wind Devil stacking?

So recently I found out that creeps can only take damage from one Thermite Mine at a time, which got me thinking.

Does the damage from Blade Spirit stack with the damage from another Blade Spirit? Same thing with 2 Wind Devils?
And if they do, do they count as “different sources” for the bleed/electrocute damage?

Anyone know?

I’m not sure about Electrocute stacking (hard to see) but Maelstrom lightning dmg definitely stack. When I fighting some boss with my druid kill speed grow drastically as all Devils get over boss.

I have tried testing this, but unfortunately this is very difficult to do as DoT damage from pets are not shown, and Wind Devils and Blade Spirits count as pets. You would have to find a mob, check it’s kill speed with 1 Wind Devil/Blade Spirit, then pre-cast 2 of them and engage and see if the kill speed is any faster. I can confirm that 2 Wind Devils don’t have their physical damage stack on the same target however.
