Mastered Ultra Instinct (MUI)

MUI (Mastered Ultra Instinct) is obtainable by using Dragon Ball on Hamon or Hermit Purple. It's a decent spec to choose if you're looking for something that is easy to get and good in combat. Additionally, it doesn't take very much experience to master so it's a great spec for new players.

Trivia

 * This spec at one point was the most powerful in game, it has since been nerfed and as of now is pretty mediocre
 * This spec used to be able to one shot sans and was an outstanding counter to it, that is not longer the case however
 * King Crimson/Requiem is an amazing counter to this ability. This is because MUI's attacks have such a large aoe, due to that KCs epitaph counter will be able to hit it easily and render the MUI defenseless for a brief period
 * At one point it was the rarest spec in game, however this is no longer the case and is in fact one of the most common in game
 * If you believe yourself to be somewhat skilled at the game, don't use this spec, it will only hold you back
