Old NieR (“Father” NieR)
Entering the 15 Nightmares changes NieR’s appearance to old NieR or “Father” NieR, the version of the protagonist in NieR Gestalt. This effect is, however, only aesthetic as you will be able to use weapons and magic normally. You also do not gain any new abilities in this form (to be confirmed).
How to Unlock 15 Nightmares
You can access 15 Nightmares by going to NieR’s house during the second story route (after clearing the game once and unlocking Ending A). Examine the glowing spot in the center of the first floor of the house to begin the 15 Nightmares content.
15 Nightmares Dungeons
15 Nightmares consists of a series of three dungeons which can be entered by going through a door inside the mysterious white dimension that serves as the area’s hub. At first, there will only be two doors in the hub, one that leads back to NieR’s house and the other to the first dungeon. A new door will be unlocked by clearing each dungeon one by one.
Noted that you will to start from the beginning of a dungeon if you die at any of its levels.
Recommended Level for 15 Nightmares
It is highly recommended to be at around level 30 to 40 before trying to clear all of the dungeons in 15 Nightmares. Many of the levels in each dungeon feature powerful shades and bosses that can easily kill you in one hit if you are at a low level.
Because of this, you should try accessing 15 Nightmares when nearing the end of the game’s second story route (before going to the Shadowlord’s Castle). Try to have your favorite weapons upgraded to their maximum levels as well before taking on the dungeons.
15 Nightmares Obtainable Items
Two-handed Sword with the Highest Attack Power in the Game
Going through the 15 Nightmares dungeons lets you obtain the Fool’s weapon set which consist of the Fool’s Embrace (one-handed sword), Fool’s Lament (two-handed sword), and Fool’s Accord (spear). Note that Fool’s Lament boasts the highest attack power value out of all obtainable two-handed swords in the game when fully-upgraded.
|NieR Kabuki Outfit||NieR Samurai Outfit|
The Kabuki and Samurai costumes for NieR, Kaine, and Emil are also unlocked by clearing the first and second dungeons of 15 Nightmares. Wearing these new outfits also changes the orb projectiles fired by enemies to tiny versions of Emil’s head in his weapon form.
