Nightmare Rift

Challenge Overseers and Clear Quests for Rewards!

About
The Nightmare Rift is a feature that was added in the January 28th, 2015 maintenance.

Within the Nightmare Rift are special quests that when cleared, will reward Overseers' Spirits and Runes. Collect Overseers' Spirits to obtain special units and Runes to exchange for additional rewards!

More Spirits and Runes will drop from more difficult quests in the Nightmare Rift.

The Nightmare Rift feature may be subject to change without notice.

Spirits
Each Overseer has their own unique Spirit. Any spirit you collect for a given Overseer will remain between quests, allowing you to pick up where you left off.

The Unit will be sent to your Gift Box upon collecting the predetermined amount of Spirit from an Overseer.
 * The first Unit will drop at the first 1000 Spirits collected.
 * The second Unit will drop at the next 2000 Spirits collected.
 * The third Unit will drop at the final 3000 Spirits collected.

You can challenge an Overseer even after you've received their 3 unlockable Units.

Purify
Purifying the Nightmare Rift bumps up the rate at which you obtain Spirits. By purifying, you can obtain 1.5× the Spirits for 30 minutes.

You can purify without using Sacred Stones once per day. This purify resets everyday at 5:00 AM PST/PDT. After you spend your free purify, subsequent purifies will cost 10,000 Sacred Stones.

After purification, Spirit bonuses will be shown in the Quest results screen.
