The Quantumsuit Helmet is a direct upgrade from the NanoSuit Helmet with superior defense and armor toughness. Like the rest of the QuantumSuit set, the helmet has a storage capacity of 10,000,000 EU. Like the NanoSuit Helmet, it has night vision that can be activated by pressing ALT + Mode Switch Key(M by default).
The QuantumSuit Helmet is worn as helmet, and can only be charged in an MFSU (or higher if an addon adds it, for example the AESU).
If Charged, the helmet removes oxygen underwater. It also automatically feeds you canned food.
The helmet also eliminates most de-buffs. This does not include Instability from Mystcraft ages.
