Second Sentinel is an NPC in Hollow Knight Silksong. Second Sentinel is an automaton hidden on the west side of Cogwork Core, behind a breakable wall. To activate it, you’ll need to collect three Cogheart Pieces and return to its location. Interacting with it again will automatically combine the pieces into the Cogwork Heart, reviving the Second Sentinel. Once restored, it will begin to randomly appear across certain areas, assisting by attacking enemies. NPCs are non-playable characters that players can encounter and interact with throughout the game. NPCs play an important role in the game as they provide vital information that can help Hornet in her journey. Some NPCs can provide goods and unique services, and they can supply special rewards for completing an NPC's questline.

Introduction / Initial Meeting
- Woken, is this sentinel. F-f-f-functional, is its shell. Still devoted, is this s-s-sentinel, and awaiting your commandment.
- Defence of the sacred C-c-citadel, and the voices that fill it-t-t, is our eternal duty.
- Eternal, is the Citadel. Et-t-ternal, is the devotion of the sentinels. While its shell is f-f-functional, this sentinel will hold true to its duty.
Encountered as a boss
- D-defence of the sacred Citadel, and the voices that fill it-t-t, is the eternal duty of the sentinels. Termination, is the n-n-necessary fate of all those enthralled by the whispering Silk.
- Unsure, is this sentinel. B-both haunted and innocent, you seem. With regret, this sentinel must t-t-test the strength of your will.
After defeating the Second Sentinel
- By the purity of your will... the c-c-clarity of your intent... you are innocent of the silken curse. Failed, has this sentinel. Your j-judgement, will it accept.

AnonymousThey appear later in act 3, in the area left of the upper clockwork core. They can be spoken to there. I passed by to grab my cacoon, and when I came back they had left. Has anyone else done that interaction?

AnonymousRobot waifu helps you clean the floor occasionally in the Choral Chamber after you finish their wishes

Anonymousive found its best if you want to enjoy the fight to not place your tacks or any of your other tools till after the sentinel starts attacking. I did it before and wasnt expecting to find them dashing into my face the second they woke up. hilarious but a fun fight to go through

AnonymousThis automaton boss fight whips. It's quick as lightning. Hit it with some venom floor tacks. It didn't much care for it. No, siree Bob!

AnonymousAfter beating him as a boss, he can still be found in the hallways helping you out periodically. However, he can also be found standing still in one of the rooms near the Grand Bellway station and you can talk to him. I doing know what he says though because I walked past him and was gonna come back, but he was gone. I haven’t found him since.
