Patches will now move to the Shaded Castle, he is found just outside of the boss fog, speak with him here
After this he will move back to Murkwater Cave and will act as the Boss of the cave again, however, he surrenders a lot faster this time and gives you the Patches’ Crouch Gesture. If you attack him three times he will be aggressive again, let him get you down to low HP and he will offer to accept your surrender, use the Grovel for Mercy gesture and you will get the Extreme Repentance gesture and after reloading the area he will once again be a Merchant
