World modifiers

World

Scalar global keys parse as percentages /100 with default 1. EitrRate, DurabilityRate, FoodRate and CarryWeightRate join existing rates. WorldLevel is clamped 0..10. Player-count difficulty is clamped nearby XZ count unless forced. Enemy outgoing multiplier=1+(n-1)*damageScale; damage to enemies divides by 1+(n-1)*healthScale.

Scope of the calculation

Scope of the calculation
Limit
Count range/cap and per-player factors are asset inputs. WorldLevel GetTotalDamage adds a separate enemy raw amount, so a simple rate-only damage model is incomplete.
Prefab parameters are asset-derived; live state/engine outcomes require-runtime.

World toggles

Extracted option definitions and their key bundles. UI activation depends on the active settings screen; these tables do not describe the settings of your world.

World toggles
Key	Authored default	Description
playerevents	Off	Raids are based on the progress of each individual player, rather than on which bosses have been killed on the server. This setting is recommended if you want the game to be slightly friendlier to players with different progress.
nobuildcost	Off	Build pieces require no materials to build. You still need to discover recipes as per usual.
passivemobs	Off	Enemies won't attack until you provoke them.
nomap	Off	You will not have access to the map or the minimap. This makes the game harder than intended.
fire	Off	Wood can catch fire and spread throughout the whole world, not just in the Ashlands.
teleportall	Off	Allows you to bring all items with you through portals for a more casual playstyle. This will circumvent the progression and exploration of the world as it is intended.
noportals	Off	You will not be able to use portals to teleport yourself across the world.

World rate interpretation

Absent or invalid scalar keys use the default. A percentage key is divided by the listed divisor before use; this does not replace each mechanic's additional rules.
