Can Chieftain run Siege Ballista?

I'm really not good at this game at all, so I hope that a better player can help me out here. I really want to try making a siege ballista marauder with focus on fire damage (obviously i guess), but I'm super stumped by the problems like having no dexterity to speak of, especially to make the Iron Commander bow work properly.

I'm not asking for a ready build or anything like that, just some advice.

From what I've seen, yes. Chieftain's can do a decent Siege Ballista build. But not an Iron Commander build.

A decent bow, some source of iron grip, maybe a Skirmish quiver and probably the extra totem keystone and you get up to three ballistae, and with a good bow that can easily be enough.

I've seen a build like that before, but don't quite recall where.

Ah, so Iron Commander isn't mandatory for the ballista then, I didn't know that. That makes this easier.

Thank you for answering.

You know about those attribute conversion jewels, right? If you really wanna make IC chieftain. I still have to PoB it first though to speak of robustness.
