It can only be repaired with other Enclave Power Armor. Wearing the Enclave Power Armor will increase Strength by +1, your Radiation Resistance by +10 and will decrease your Agility by -1. This means that the X-01 is the prototype precursor to the APA Mk1 BUT the creation club calls the APA Mk2 the X-02 which means the X-01 isn’t the prototype but rather retcons and replaces the far better looking APA Mk1. The Enclave Power Armor is a variation of the Advanced Mk II Power Armor in Fallout 3, worn by the Enclave Soldiers. THEN we got Fallout 76 where it tells us that the X-01 was designed by the Appalachia branch of the Enclave and transmitted to the Oil Rig when the bombs fell before contact was lost. Then we got Fallout 4 where this “new” design (x-01) shows up all over the map (in places not touched since the bombs fell) and it resembles the Advanced Power Armor Mark 1 but we know it can’t be because the APA Mk1 was created by the Enclave after the bombs fell.
In Broken Steel we then got to see the Hellfire Armor (the lore of which was expanded on in New Vegas through ED-E). In Fallout 2 we were introduced to the Advanced Power Armor Mark 1 (we also got to see the Mark 2 but it looked the same as the Mark 1), then in Fallout 3 we got the “Advanced Power Armor Mark 2” which was halfway between a Bethesda-style retcon (due to dialogue with Henry Casdin) and an evolution of the Enclave’s design.
