Not every character, including your Pawns and NPCs, is immortal in Dragon's Dogma 2. So it's not like they'll just reappear at your base after they die. Instead, you'll have to put in the effort to revive them using a Wakestone. If you think that reviving someone is an easy task, think again, because more often than not, you'll lose their corpse. Even if you do lose it, don't worry, because it's still possible to revive that dead character in Dragon's Dogma 2. Our guide here will explain how.
How to Revive NPCs That Have Died | Even QUEST NPCs ► Dragon's Dogma 2
As I said, you need a Wakestone to revive Dead Characters in DD2. To get one Wakestone, you need 3 Wakestone shards, and let me tell you, these shards are rare to find. Anyway, 3 Wakestones will automatically turn into 1 Wakestone in your Inventory. So all you need to do is get closer to a dead character and use the Revive prompt to save them.
Note: Wakestone Shards can be purchased from in-game merchants, online stores, or treasure chests.
If you lose the corpse, you can somehow find it in the Battahl Morgue or Vernworth Charnel House, whichever is closest. All you have to do is go to the Morgue Attendant and tell him that you are looking for a corpse. You can then select a dead character from the list and a candle will be placed next to their coffin. This is done so that you can identify the correct coffin. Once you are near the coffin, you can interact with it to revive the dead character in Dragon's Dogma 2.
