Game Basics 2
Kin

. Kin are dismissed when they die and cannot be summoned again until a certain amount of time has passed. Kin slowly recover HP while dismissed or not in combat.
You can enter a compact with a new kin from a new summoning circle even while already in a compact with a kin. However, the compact with the former kin is broken, and if that kin's level was increased, it will lower.
Alliances
Petition another player for an alliance by holding down to show the Function menu and pressing 
. If accepted, you are allied, and the petition confers the following effects.
Prevents attacks from hitting allies.
Shares Sword Virtue and Pledge Virtue with allies.
Grants the Fellowship Medal, which allows you to teleport to allies.
You can abandon an alliance at the end of each phase, at the cost of your maximum HP.
Co-Op Battles
Co-op battle requests are sent to nearby players when a battle with a trespasser begins. Accepting the request transports you to engage in battle against the trespasser. Players participating in the battle will not be able to hit each other. If they defeat the trespasser, participants are granted Repulsion Virtue and Powers of Blood.
Once the co-op battle is over, you are returned to your former location.
Sigils
Sigils establish relationships with other players; you can earn Virtue by completing the unique goals of the Sigils. There are a variety of ways of finding the target of the Sigil, such as using a specific item or sensing their presence when you get close. Determine if a player is a target by locking on to them.
A passive Sigil may appear depending on other players' Sigils.
