Arc Raiders Bastions, one of game's most powerful robots, can be found in Stella Montis. To buy arc raiders blueprints, you must kill the giant minibosses and then find them. As their spawns can be interchangeable with Bombardiers (which are also destructive), finding Bastions is a bit unpredictable. But there's a place they always seem to spawn reliably at the moment: Stella Montis. I will explain how to locate Bastions as well as where you can get their Cells.
There are many places where Bastions may spawn, but we have only seen them in the lower Loading Bay section of the central Arc Raiders Stella Montis Map. Every time I come back to this map, there is always a Bastion on the lower level. It's convenient to be able to shoot at it on the higher levels. This is an advantage you will not get in most maps. The enemy can still fire at you, but the cover is plentiful and it's very easy to retreat and heal. I haven't found a better locati0n to hunt them in Arc Raiders.
Bastions are vulnerable to two things: the yellow joints in their legs and the canisters on their back. The yellow joints on the legs and the canister on their back are both weak points. You should target them with explosives or armor piercing attacks. They will stun a Bastion as well as do significant damage. The back canister can be destroyed to reveal a tank that is an even stronger weak spot.
If you want to hunt Bastions, bring along heavy weapons and fire attacks. The Bastion is slow, so it will have trouble avoiding or moving out of an area that's on fire. Arc Raiders weapons or equipment are good for hunting Bastions.

Make sure to check every piece after the bastion is destroyed! Rare Bastion Cells may appear multiple times per Bastion slain, so you could get less than the full reward if you forget to check a metal piece.
You'll require Six Bastion cells to upgrade the Gear Bench up to level 3. If you do not share your resources with anyone, this will mean you need to kill and harvest at least two Bastions.
