Question: dark souls 3 how to join other players?
Answer: To be summoned into someone else's game, you'll need a White Sign Soapstone, which you can purchase for 500 souls from the Shrine Handmaid in Firelink Shrine. Use the White Sign Soapstone to draw your own summon sign on the ground, and it will appear in other players' games, just as summon signs appear in yours.
