by Palpatine to be stiff, uncomfortable, and downright as painful as possible for Vader. This served to do 2 things. One, it kept Vader in a constant state of pain, which fueled his anger and made him stronger, and 2 it served as a persistent reminder of his failure. and of his lost potential.
Inside his suit and mask, Vader has a series of needles in his skin. Unfortunately, these needles, which transmit neurological data throughout his body and allow him to control his limbs, also cause him constant pain.
While Vader was being reconstructed and operated on, Palpatine made sure that he had no anesthetic. so that he would become stronger in the Dark Side. through his pain. However, Palpatine also secretly sabotaged Vader armor, giving him outdated technology.
But Palpatine also knew that, like any good Sith, Vader may one day try to usurp him. This informs his decision to give Vader obsolete tech for his suit. A cheap move perhaps, considering the technology keeping Vader alive is technically older than anything used during the Clone Wars by a decade, but an effective one.
He believed that the Jedi's lightsabers, created as the order's primary weapon, clouded their vision and blinded them to the fact that everything around them is a weapon through the Force, and that the Jedi put too much stock in lightsabers.

5 Putting Vader Through Agonising Life-Saving Procedures
Darth Vader is horrifically wounded after his duel with Obi-Wan Kenobi on Mustafar in Revenge of the Sith, having three of his limbs removed and being burned after his clothes catch fire.
After Darth Vader refused to kill both Luke Skywalker and Padmé's body double, Sabé (which would've threatened his manipulation of him), Palpatine punished him by attacking him with Force Lightning.
If he hadn't been placed in his new armour and had been left on Mustafar by the Emperor who was disappointed with his failure to kill Obi-wan then he would have died. If he had won the battle then his force powers would only grow and it is estimated that he would be about twice as powerful as Palpatine.
With that being said, if Palpatine did, indeed, use Force-healing to keep Vader alive, he didn't appear to have given enough life force for it to take a toll on him -- and being as close as Vader was to death, Palpatine would have required a lot of energy to keep him alive.
The novel explained that, had Vader killed Obi-Wan on Mustafar, he would have tried to kill Palpatine too, but given how badly wounded he was after the duel, his power wasn't the same and he was weak, both physically and mentally.
The apparatus of Vader's mask was designed to support his breathing. The armor's boots featured magnetic clamps, which could magnetically adhere the suit to a metallic surface, while the legs were heavily armored and able to withstand at least glancing blows from a lightsaber.

Apparently, Sidious had no interest in the weapon because he left it behind when he took Maul captive. Mandalorian Prime Minister Almec, who orchestrated his escape from prison, informed the powerful Sith that some of his followers had recovered the Darksaber.
Yoda saw his lightsaber as a weapon and a meditative tool, and vowed to never use it again as an act of penance for his involvement in the Clone Wars. Yoda chose to teach Luke Skywalker to be a true Jedi Knight without relying on combat, emphasizing the importance of selflessness over fighting.
Kylo Ren's obsession with Vader is clear, but Star Wars never explained how he acquired the helmet. It is speculated that he may have found it himself on Endor, or it could have been passed down to him by Supreme Leader Snoke.
At the same time, Emperor Palpatine's™ droids designed it to act as an advanced life support system. His armor was wired with complex equipment to monitor his respiratory, pulmonary, and neural systems, together with a separate heartbeat regulator and special breathing apparatus to keep him alive.
The phrase appearing on the prop is believed to read: “מעשיו לא יסלחו, עד שיגיע” The syntax of the phase is disputed by Star Wars viewers familiar with Hebrew but some of the most popular translations of the Hebrew phrase are: “His deeds will not be forgiven until he merits,” “My actions didn't go away until they came, ...
