When equipped, the Agape Ring will make the wearer unable to gain souls from any sources. It will also cause soul items, such as Soul of a Proud Knight or Soul of the Last Giant, to become unusable until the ring is unequipped.
The primary purpose of this ring is to lock Soul Memory at a specific matchmaking bracket for the purposes of PvP. By preventing the increase of Soul Memory, players are able to continue matchmaking at specific locations where lower-level players are more commonplace. This can be particularly useful for members of the Brotherhood of Blood covenant, who can continue invading in specific areas of the game regardless of game progress, or for members of the Heirs of the Sun covenant, who can continue to be summoned for specific areas and bosses without being pushed out of range by soul bounties.
