NPCs are non-playable characters that players can usually interact with. Below is a list of all NPCs in Dark Souls II and their functions. If you kill an NPC, a tombstone will appear at their original location. The appearance of the tombstone is not immediate and can take quite a while, multiple hours of gameplay may be necessary depending on how many NPCs you've slaughtered. If multiple NPCs are killed, tombstones will appear in order of the NPC's death. Players can visit tombstones and pay souls to resurrect NPCs as ghosts. Ghost NPCs provide the same functions they do as when they're alive. If the player is killed after reviving an NPC, payment will be required to resurrect the NPC again.
