# LifeSteal LifeSteal is a server-side mod recreating the LifeSteal SMP experience. The number of maximum hearts can be set via the gamerule `lifesteal:maxHearts` (default: 20). The grace period is the period when the PvP is deactivated. It is scoped at the player-level and not at the server-level. A player in the grace period cannot be attacked and cannot attack others. The time (in minutes) of the grace period can be set via the gamerule `lifesteal:gracePeriod` (default: 30). Hearts cannot be crafted by a player at/above 10 hearts. You can enable this via the gamerule `lifesteal:canCraftHeartsAboveVanillaMax` (default: false).
