When Fontaine was first introduced in Genshin Impact, players will learn of a new feature called the Bond of Life. However, this feature is mostly negligible until the release of Arlecchino in version 4.6, where she ensures that the mechanic actually holds significance. Unfortunately, like a two-edged sword, Arlecchino bringing attention to the mechanics of Bond of Life isn't entirely beneficial since her abilities work against the normal system.
