You must complete the first few steps of Act III: Crossed Blades to access this quest at the Shaping Slab. The mission requires completing a series of objectives in The Nether. Since most of these must be completed at your own pace, we recommend running Nether: Private. This will prevent random teammates from pushing forward while you are working on an objective.

In this guide, we will cover everything you need to know about the Witch’s Gambit quest — including its requirements and the most efficient ways of completing them in Destiny 2: Heresy.

Since discovering multiple secrets in a single run can be time-consuming, we recommendloading in,completing one secret,then restarting. The following is a quick rundown of all the secrets:

Toland

Anywhere

You willneed to locate Toland, follow it around the Dreadnaught, andopen the chest where it eventually stops.

Vorok, Excise Eternal

Trenchway, Hall of Souls, Mausoleum

You will see three braziers in various locations. Simply light them tosummonVorok,Excise Eternal– a yellow-bar Hive Knight. Defeat him to complete the secret. He doesnot have much HP, and canalso be disoriented, making it incredibly easy to deal with him.

Taken Blights

There arethree Taken Blights in Mausoleum– in the boss arena.Shoot these Taken Blightsto spawn a chest, which will complete a secret. Remember that these Taken Blights aremuch smaller than the ones in Public Events.

Rites of the Deep Tithing

Trenchway

In the Trenchway, offerRites of the Deep Tithe at the altar. If it is lacking, ask a friend who has it to help you out. All you need to do is to enter the portal and loot the chest.

Heretical Altar

Mausoleum

While in the Mausoleum,destroy a Shriekerin front of a Taken Portal. Enter it toreach the Heretical Altar. Open one of several chests to complete a secret. Opening a chest will kill you, but it is intended.

The Ravenous

Hall of Souls

In the Hall of Souls,locate a yellow-bar Thrall named The Ravenous. You need to have him follow you into the adjacent room where it will begindevouring some wormson the ground. Once it grows into an Acolyte, break your line-of-sight, and follow it to its next location.After it transforms into a Hive Knight, kill it, and loot the chest to complete another secret.

The fastest method to complete this step is to complete the Toland secret, relaunch the activity, and repeat until you have finished all three secrets.

Complete Encounters

Next,complete encounters in The Netheruntil you reach 100 percent progress.Summon your Ghost,follow the white marker,and continue running the encounters.

If you do not wish to engage bosses,restart after every two waves. However, we do recommend completing the boss rounds, as they provide the most progress.

Kills With A Corrupted Boon

The last step is todefeat 100 enemies in The Netherwhile you are under the effects of a Corrupted Boon. Corrupted Boons only appearafter the completion of an encounter. As the name suggests, these Boons have an upside and a downside. For instance,Sharpshooter’s Burden is a Corrupted Boonwhich says:

It increases all Precision Damage.

You take increased damage from all the sources.

It is advised tochoose a Corrupted Boon as early as possible. Doing so will help you stack up 100 kills while working on other objectives.

Once you have completed all the steps, return to the Shaping Slab in Eris’ Apartment to getSeasonal Gear,some Sigil Shards, anda few Essence of Desire.
