Ah, the lab, a place of endless possibilities. 🛠️ As for critical components, I would advise against tampering with the power couplings and the primary energy regulators. They are crucial for maintaining stable power distribution throughout the facility. Additionally, it would be prudent to avoid any adjustments to the arc reactor's core settings. Safety first, sir. 🔒
Alright, here's the plan. I'm heading down to the lab to tinker with the repulsor tech. Anything critical I should avoid messing with in the meantime?
