Just Like That One Video
There is an Achievement/Trophy in Tiny Tina’s Assault on Dragon Keep called; “Just Like That One Video”. It requires you to defeat the Darkness, a hidden enemy within the game that has a specific requirement in order to successfully defeat it.
The Darkness is a unique enemy in Tiny Tina’s Assault on Dragon Keep. It is located on the map Hatred’s Shadow. Once you spawn in make your way through “Throgmuk’s Precipice” and once you reached the end of the Orc encampments. Don’t go inside and enter The Pits where you meet Sir Gallow. Continue to the right, there you will find a campfire and two sleeping bags. Directly to the left is a black void called, The Darkness.
You can open the secret door in Hatred’s Shadow by defeating the Darkness with the spell Magic Missile. If you use any other weapon, the Darkness will disappear, however, the door will stay locked.
You can get the Magic Missile Spell/Grenade Mod by defeating Wizards, Necromancers, or Handsome Sorcerer. If you are going to farm one, seek out Badass Wizards as they can drop a Purple/Rare variant. These are an x4 variant instead of a blue x2 variant. You can farm Badass Wizards in the ‘Temple of Misworship’ which is located in the ‘Lair of infinite agony’.
The Achievement “Just Like That One Video” is a reference to a D&D video where one of the players wants to cast a spell called Magic Missile. However, since there wasn’t anything in the room, the player calls out “The Darkness” as its target.
