Greirat NPC Side Quest
Accept his quest and unlock his Merchant Services at the Firelink Shrine. He will ask you to get Loretta's Bone which can be found on a corpse hanging from a balcony overlooking a congregation in front of a huge bonfire(Undead Settlement). He will ask for permission to scavenge for more items. He will return following the next boss kill and returns as early as after Curse-Rotted Greatwood.
To trigger his second scavenging quest you need to cross the bridge to the Boreal Valley, but this needs him to be Alive. Talk to him and he will offer you the Curl up Gesture. During your exploration make sure you meet him in the kitchen in Irythyl which is right next to the Sewers. Don't explore Irithyll Dungeons or the Profaned Capital before killing one boss as this will cause Greirat to die.
You must continue with Siegward's questline as he is the one who can who can save Greirat, but he'll need his armor for that. Once he is back safely after the Next Boss fight, he will offer you to pillage if you've defeated the Dancer of Boreal Valley. Do not let him go out for another hunt as his won't make it back safe.
Killing Greirat for his Ashes will only unlock the wares that he was selling before you kill him. Killing Greirat while both Patches and Greirat are in Firelink Shrine will make Patches hostile toward you.
