What level Artificer would you have to be to have all those automatons?
I'm not sure, but I think there is a control center which has this function, independent of the Artificier level? I mean as a Battle Smith you have a Steel Defender and as a LVL 15 Artillerist you can have two Walking Ballistas. Technically, you can certainly build infinitely, but probably for more than two you need a fixed location with a control center that has a certain radius within which it can then control the automatons, instead of the Artificer itself.
At least that's how I imagine it, if I had to face Gortash, I'd probably try to get straight to his command center to get rid of the Steel Watch as quickly as possible.
BTW a good target for the Ironhand Gnome's rune powder bomb!
