I made a new Auto Axe

As the title says I decided to make a new Auto Axe but I may have screwed up. I made it for soloing EN06 so I used these mods for the first 3:

Troubleshooters Heavy Hitters Defenders

Now this is where I may have screwed up. I added Vipers as the 4th star and added Poisoned as a mod. Can a robot be poisoned? I really thought I was being clever until I thought about it for a second.
