/lifespan

The optional Reincarnation mod provides /lifespan. Every node requires gamemaster permission (operator level 2), including self queries.

Command	Behaviour
/lifespan or /lifespan get	Query yourself
/lifespan get <targets>	Query selected entities
/lifespan set <targets> <ticks>	Rewrite remaining and total life; non-negative ticks
/lifespan add <targets> <ticks>	Positive values extend both numbers; negative values spend remaining life only
/lifespan unlimited <targets>	Close the ledger until explicitly granted finite life
/lifespan reincarnate <targets>	Queue rebirth using Reincarnation's configured mode

Writes affect living targets. Values use game ticks and still write while natural ageing is disabled. Rebirth feedback means the request was accepted; lifespanRebirth Post or Failed reports its outcome. A full rebirth replaces the player; an in-place reset keeps the same entity and life number.

The command is available when Reincarnation is installed and is controlled by that mod.

Queries display age / total lifespan, with age increasing over time. set/add still take lifespan grants in ticks.
