As in previous Souls games, Patches attempts to fool or otherwise deceive the player into performing various actions which will allow Patches to attempt to kill them, in the aim of looting their bodies afterward.
Patches can be first encountered in the Cathedral of the Deep, after taking the elevator up near the entrance to the Deacons of the Deep boss room. He will be standing next to a bridge wearing the Catarina Set, attempting to trick the player into believing that he is a knight of Catarina and that he has spotted treasure on the other side of the bridge. Upon reaching the middle of the bridge, a cutscene occurs where Patches will lower it in an attempt to have the giants kill the player. If they have already killed both giants, he will scold them for doing so.
When the player returns to the area where they initially encountered Patches, they will find that the bridge is still lowered but that he has moved to the other side, removing the armor in the process. In order to reach him, the player will have to make their way up to the rafters of the cathedral and drop down, this is the same path taken in order to reach Rosaria. Upon talking to Patches, he will act as if he has never met the player before. Upon confronting him about the matter, he will claim that the armor possessed him, and he will grant the player the "Prostration" gesture and a Rusted Coin as way of apology. After this, Patches will become a merchant.
Patches can be encountered later at Firelink Shrine, or make his first appearance here if the player raised the bridge from Rosaria's side without encountering Patches. If the player enters the tower adjacent to the shrine (the one which requires the Tower Key) and takes the elevator to the top of the belfry, Patches will close the gate and lock it behind the player. Returning to the gate and talking to Patches will cause him to taunt the player, stating his intention to loot the player's corpse when they die in the tower. The only way out is to reach the bottom of the tower by dropping down onto the coffins that stick out of the wall, or by using a Homeward Bone. Upon returning to the initial meeting place, the player can re-open the gate but Patches will be gone; he will have relocated to the upper level of the shrine, on the right side near the Giant Tree (the player may need to leave and re-enter the area, triggering a loading screen in the process, to cause him to spawn there). If the player confronts him here and refuses to forgive him, he will reward them with a Rusted Gold Coin and will now act as a merchant.
Upon reloading the area, talking to Patches will reward the player the "Patches squat" gesture.
Talking to Patches will reveal that he and Greirat of the Undead Settlement are acquaintances. If the player has sent Greirat to pillage Irithyll of the Boreal Valley, Patches can be asked to save him. If the player has not purchased the Catarina set from Patches, and tells Patches about Greirat's whereabouts, Patches will disappear from Firelink Shrine. Upon beating an area boss, both Patches and Greirat will return.
