Back From The Dead
Pardon me. ILS said "except for Drain", which I misread. I could've sworn Maul's shown Beast Control at some point, though.
Anyway, here's the thing. Maul's definitely underrated and deserves some credit. But the arguments here seem a bit strange - some things that happen quite a bit in the mythos are being brought up as huge for Maul, yet it's not considered that way in the cases of other characters?
"Being trained in Sith lore" or perusing the archives? That's incredibly vague and we don't know how much he had access to or how much time he spent in there. And learning powers from there and then practicing them etc. is another thing entirely. I also like how Maul looking at the archives to an unspecified extent or Dooku having a shelf of ambiguous holocrons is treated as such a big deal, yet Atris, who on top of whatever she had access to as the Head Archivist of the Order, studied dozens of Sith holocrons which specifically contained teachings of combat and the Force, is dismissed as having knowledge of no particular note.
That said, somebody needs to post the quote pertaining to Maul's ability to peruse the archives for more detail - because "studying Sith lore" or whatever Beni posted means the square root of jack shit. I'm sure Maul has better.
Maul's survival and Sidious being surprised is kind of dumb and comes from Sam Witwer, who isn't an official source (worth taking into account, but it's much like the author quotes). In the context of Canon, it is a big deal, but as we're discussing Legends here, it's not that big of a deal - nor does Witwer's quote hold in Legends because the Plagueis novel specifically has Plagueis revealing to Sidious about Gean surviving her duel with Gravid, where she survived worse injuries than Maul. Sion also gets mentioned in Darth Plagueis.
To elaborate on why it's just a showing of immense hatred, not a showing of knowledge, and not that overwhelming in the grand scheme of things - ****ing Maw was able to survive after being cut in half. Sion held his body together despite the flesh itself being ravaged, mutilated and decomposing, and his skeletal fracture having several thousand fractures and breaks. His whole body shouldn't have even been kept together, yet it was - through nothing more than sheer will and hatred. The same goes for Maw. Maul surviving the bisection was through sheer hate, not Force knowledge, based on how others in the past have survived that sort of stuff. That Jedi who claimed "I believe Maul's knowledge of the dark side kept him from dying" is full of shit and I'm not sure why they're being taken as an accurate databank of knowledge on the dark side of the Force. They obviously don't know much about it and it's purely their own speculation. You're reaching if you think it's anything else.
Maul clearly survived on hate, based on both past displays of the same showing as well as the scan of Maul after he tumbled into the abyss. Every other source relating to Maul's survival also claims it was rage and hatred that sustained him, and no other source to my knowledge (certainly no official ones) claim that it's due to knowledge.
Bottom line - it's not a feat of Force knowledge, and it's been replicated by Force users who are widely claimed to be among the weakest named Force users in history. It's not nearly as big as it's made out to be, unless we're also putting Maw and Sion high up. 👆
Also, IIRC, Lucas does say at one point that Maul/Dooku were expendable but Anakin wasn't - I'll have to find it.
