World Tendency

World Tendency is a gameplay mechanic in Demon's Souls.

General Information
World Tendency is a mechanic that affects the difficulty and triggers special events. Each area of the game has its own World Tendency stat, though instead of being represented in discreet numbers, it is shown to the player as a brightening or darkening of the five archstones seen in the World Tendency menu.

World Tendency can fluctuate unpredictably online, as tendency will shift to an unknown average that is aggregated from the playerbase. In offline play, the tendency will only depend on the player's own actions.

Effects on Gameplay
The closer an area is to pure white tendency, the weaker enemies become. However, non-boss enemies will also give fewer souls on death and have a lower rate of dropping items. The opposite is true for shifting towards pure black tendency; Enemies become tougher and deal more damage, while offering more souls and having an improved drop rate.

In addition to affecting the overall difficulty, various special events can occur:
 * The opening of optional areas
 * The appearance of friendly or hostile NPCs
 * The appearance of Black Phantom enemies
 * The appearance of Primeval Demons

Changing World Tendency
The following actions will increase or decrease the World Tendency value in the archstone that they occur: Note that each area's World Tendency begins at a neutral value of 0, and caps at maximum of +200 or a minimum of -200.

Keep in mind that killing some of the listed NPCs affect your Character Tendency in positive or negative ways. Dying while in Body Form in Nexus prevents a Tendency change in another world, and Nexus has no events tied to World Tendency.

Specific World Tendency thresholds (Neutral, Neutral Black/White, Black/White, Pure Black/White) should be written in this section.

Effect on Enemy Strength
Enemy HP has three opportunities to decrease as World Tendency values increase: Enemy HP remains at 100% when below 50 World Tendency, it does not increase further when shifting into black tendency. This effect applies to both regular enemy mobs as well as NPCs.
 * +50 to +99.9 = HP at 95%
 * +100 to +149.9 = HP at 90%
 * +150 to +200 = HP at 80%
