Entering any covenant found throughout Lothric affects the multiplayer mechanics in various ways.
Completing duties for a covenant grants the player certain tokens, which can be returned to the covenant leader to unlock unique rewards.

Covenants can be switched on the fly by equipping their respective covenant item.
