I love the new multiplayer and I thought to myself, why not add multiplayer only relics.
I have a few examples, how to unlock them and what they do.
Ghostly heart- reviving players costs less hp (stackable)
Unlocked by reviving 10 teammates not shared
Banquet plate- eating food heals nearby allies by half the amount
Unlocked by having each player eat every food in 1 delve SHARED RELIC
Binding chains- when teammates go too far they teleport to you
Unlocked by teleporting to allies 5 times SHARED RELIC
Thief’s hand- lets you steal 1 item from an ally or from the merchant, this does lower discount by 10%
Unlocked by taking another persons relic that they have earned (for example someone opens a chest and you take the relic) not shared
Sacrificial totem- upon dying you get a revive, costs 50 coins VANISHES ON DEATH
Unlocked by taking a fatal blow to save another player
Paladins shield- when players are in a certain distance of you they take less damage (becomes useless in NG+++)
Unlocked by parrying a projectile which is about to hit an ally
Necromancers staff- revives players for a cost of a random relic from a random teammate
Unlocked by being revived 25 times
