Defictionalization: There's a real-life Twilight's Edge forged by the Youtube channel "That Works", made from a solid block of steel. Although it's not for sale and is commissioned by Netmarble, the provider for the mobile game.
There is a clan-based PvP faction area called "Ethereal Battlegrounds/Hell Island/Floating Island" unreleased outside Korea.
There is one sealed-off dungeon in Songshu Isle just sitting along the main quest path with no way to unlock it. A glitch allowed one player to enter and see it only has a single room inside, but digging deeper, discovered it was connected to a dummied out quest.
Executive Meddling: According to the localization team, the NA version of Blade and Soul was affected by this, which is one of the reasons the localization is spotty, to say the least. One notable example are the words "jyan" and "jyansei", used to describe (for lack of better terms) "warriors with great potential" and "master warriors" respectively, which are entirely made up at the behest of the execs, who apparently wanted the words to be (paraphrased) "easier for Westerners to digest" but still sound like they belong in a martial arts fantasy setting.
Schedule Slip: NCsoft has been accused of this by western gamers, due to nothing being said about the game's development for years since the announcement of the western version (the Korean version had a similar experience; see "Timeline" note). During that time, the official website also never really updated, so there wasn't even any indication that the game was being worked on at all. This was averted in July 2015, when the western version was finally announced as being in development, along with the website getting a revamp and regular updates, as well as NC Soft utilizing social media sites like Twitter to keep gamers updated on its progress until its release in 2016.Timeline The first announcement of the game was in 2007. The Korean version didn't get released until 2012 (though during this period, as the first version of Blade and Soul, many MMO news sites kept gamers updated with this version's progress), while the Chinese, Japanese, and Taiwanese versions weren't released until 2013 and 2014. The NA/EU versions were revealed to be in development in 2012, the same year that the Korean version was released, but didn't begin to have updates regarding its progress until 2015, where a late 2015 release date was given for these versions (the NA version ultimately came out at the beginning of 2016). This translates to western gamers waiting at least eight years since first hearing about the game (and four years since the Korean release) to get their version to play.
There is a platforming section that is otherwise missing from the game itself.
The Summoner class is reworked from a dark caster to a Kid-Appeal Character with a cat companion. The demon summoning aspect is reworked into Warlocks.
Most story content shown is otherwise different or missing from the main game. For example, there is a man being chased by a winged griffin, two Lyn NPC's that heals wounded characters, and a Jin woman talking to the Player Character, all of which are missing from the final game.
Classes are shown using skills that didn't make the final cut. For example, Kung Fu Masters growing wings when using their buffs, which the animation is transferred to Soulburn users.
The Gunner class is speculated to be released early thanks to its appearance in one scene, but is delayed and is turned into a more mobile class that uses hooks.
