In Specter of Torment the Phase Locket appears in the gear tab as the Keepsake Locket and keeps track of how many knights have been recruited to The Order of No Quarter.
The Keepsake Locket holds significance to Specter Knight. At the start of the game and after every level, Specter Knight is seen reminiscing with the locket on the balcony of the Tower of Fate. As the campaign goes on, it is revealed it was a family keepsake of the departed Luan, and Luan had given it to Donovan, because he had considered him as family to him.
When Donovan died and was resurrected by The Enchantress, the locket was used as a means to insure Donovan would gather the 8 knights for the order as he had promised. When 8 Knights swore allegiance to the Enchantress, the locket would then be able to reverse death itself and bring one person back to life, but only once.
After Nightmare Reize was defeated at the end of Specter of Torment, The Enchantress sought to make Reize the final knight, but Specter Knight chose to swear loyalty to her in Reize's place, finishing the deal and granting the locket power, which Specter Knight chose to use on Reize instead of himself, protecting Luan's son from an undead lifetime of servitude to The Enchantress with his final act of free will.
- The Phase Locket is the only item in the game which has a connection with the three current campaigns.
- When he was alive, Specter Knight received the locket as a gift from his friend Luan, which is later stored inside a chest inside Specter Knight's secret room at the end of Specter of Torment.
- In Plague of Shadows, Plague Knight finds the Phase Locket inside Specter Knight's secret room, where he trades the locket with Chester in exchange for the Leech Liquid.
- In Shovel of Hope, Chester sells the Phase Locket to Shovel Knight after getting it from Plague Knight.
