I have been playing a ton of Hollow Knight as you probably are aware and I have been attempting to complete every ending. Obviously, given the nature of this post there will be heavy spoilers below. Here are the Hollow Knight Ending achievements.
Achievement: The Hollow Knight – Defeat the Hollow Knight and become the Vessel
Collecting all three major essences, unlocks Hollow Knight’s final boss battle. Head straight to Hollow Knight battle and win to unlock the normal ending.
Sealed Siblings Ending
Achievement: Sealed Siblings – Defeat the Hollow Knight with Hornet by your side
Collect/destroy all three major essences (the masks on the door to the temple) and then assemble the Void Heart Charm. Then when you fight Hollow Knight, DO NOT use the Dream Nail when Hornet wraps it up, but rather finish it off with simple melee attacks.
Dream No More Ending
Achievement: Dream No More – Defeat the Radiance and consume the light
Repeat the steps in Sealed Siblings, but use the Dream Nail on Hollow Knight. This triggers the hidden boss fight the Radiance. Defeat the Radiance to get the best ending.
Note – You can do both the Sealed Siblings and Dream No More Endings in the same playthrough. Simply load in after beating the game and do the other ending.
Passing of the Age
Achievement: Passing of the Age – Aid the Herald in moving on
Find Mr Mushroom throughout Hallownest during a playthrough to unlock this after credits scene.
The Dream No More ending is easily the best of all of the endings in Hollow Knight. This ending is made even more interesting by the inclusion of the Mr. Mushroom end credit stinger which implies there is more to come in the Hollow Knight story!
