Base decay - Wiki

Protection

RSS uses its own decay timers and checks protection every five minutes. Protection applies to structures owned by you or your current in-game group.

While at least one owner or team member is online, up to 2 bedrolls protect a 24-metre radius and up to 8 claim flags protect a 32-metre radius for that team.
A generator protects its live range while it is switched on and fueled.
When the last owner or team member disconnects, the base receives 4 hours of offline grace, or 8 hours when the owner is VIP. Grace works without a generator and cannot be restarted by removing or refueling one.

Use /base near an owned or team structure to check coverage, fuel, protection time, active sources, offline grace, recent activity, and base logs. /baselog opens the team log for the previous six hours.

Unprotected lifetime

Wood structures: 48 hours
Metal or brick structures: 72 hours
Doors, windows, and hatches: 24 hours
Vault doors: 36 hours
Lockers and metal storage: 36 hours
Wood storage: 24 hours
Wood barricades: 12 hours
Metal barricades: 24 hours
Mines, claymores, snares, and sleeper triggers: no RSS decay timer

VIP doubles the unprotected lifetime and enables decay warnings.

Upkeep and repair

A single main base is selected for each owner or group. Fund its shared upkeep pool with the configured wood and metal items. When the pool is funded and the base is not raid-blocked, damaged structures repair 1% of maximum health every 3 minutes. VIP bases use a 1-minute repair interval. Empty pools do not repair anything.

Generator bonuses

Portable generator, default: 24 hours at full fuel, with 2x its vanilla wire range.
Portable generator, VIP: 36 hours at full fuel, with 3x its vanilla wire range.
Industrial generator, default: 72 hours at full fuel, with 2.5x its vanilla wire range.
Industrial generator, VIP: 108 hours at full fuel, with 3.5x its vanilla wire range.

The generator must be switched on and have fuel remaining. Removing fuel or refueling does not restart offline grace.

Selected high-value drops remain longer: raid explosives for about four hours, launchers for about two hours, and selected weapons, ALICE packs, and filters for about one hour.
