Communion is a Caryll Rune in Bloodborne.
| "A secret symbol left by Caryll, runesmith of Byrgenwerth.
Several runes relate to "blood", including "Communion",
which raises the maximum number of blood vials one may carry.
This rune represents the Healing Church and its ministers.
Blood ministration is, of course, the pursuit of communion."
