Creates a red summon sign, allowing others to invite the player into their world as a dark spirit.
- Follows the same general rules as the White Sign Soapstone.
- Being summoned into another world via red sign allows the player to retain their 130% health bonus if they are a Host of Embers in their own world.
- Red signs are still visible in areas where the boss has been defeated, and regardless of whether or not the host has an active Ember. This allows players to summon others for duels or other purposes, regardless of host status or area completion status.
- A host can summon up to two dark spirits at once, regardless of area completion status. Dried Finger will increase this number if the area boss is still alive, allowing up to five summoned red spirits to coexist simultaneously.
