Although it's off-topic...because this is to talk about the quests of this game, not of a single feature ... go to your training room, select a training, bottom right you should find the turbo-mode-button.
Note: afaik you have to be lvl 70 or higher
@CuelanGifted Psychopath requires many hours of practice to earn, especially for strength training. Accuracy and critical are fairly easy to earn super gold combos in, while defense and dodge take a little more time, and strength training seems almost impossible. However, if you train hard and upgrade your training facility and your sword to the maximum level, you will not only find that the training becomes progressively easier, but you will also eventually level up enough to earn the final quest.
Eternal Champion is earned by completing survival mode, which is easier when done at a level of at least 200. Keep training all 5 skills even if you have earned some super gold medals, and make sure your stats and talents are maximized. Experiences may differ, but I earned this quest with all 5 skills at around 50,000 in the statistics tab.
what is the turbo button it just says off all the time anyone know what it is or why it's there
It lets you start from combo 25 (as opposed to combo 1) in each training minigame. It's massively helpful for getting the super gold medals for the Gifted Psychopath quest, cause you get to skip past the really slow part at the beginning, so each run is a lot faster.
It only unlocks when your character is at about level 70, so you might have to level up a bit more.
Well, I think I'm done trying for 'Gifted Psychopath'. This is the single hardest quest I have encountered so far. Granted, I haven't earned that many, but still, seeing your reaction to it ('your' as in 'you people who are very high on the leaderboard and actually try to get as many quests as possible') means that we share a similar opinion on it doesn't it? You have to be really dedicated to get this and I'm not in the mood to unload dozens of hours on this just to get it. I may come back to it someday, but for now, I think it's best to leave it aside.
Still, thanks for the tips guys, all of you. They helped raise my pathetic combo scores in nearly every stat, I even managed to do the super gold critical combo. It's been some big help
The Give Up 2 and the BH 2 quests are probably the worst. Give Up 2 for obvious reasons and BH 2 because Akron is an annoying pita who loves spamming random shots.
