Overview
Link (联动, liándòng) is Honor of Kings: World's party quest-sharing feature. When Link is established between party members, approaching a linked teammate automatically enrolls the player into that teammate's active quest progress. This lets a single party complete multiple quests simultaneously without each player needing to hit the same quest triggers independently. Source: primary text and launch feature round-up.
How Link Works
The primary description, translated: "when the Link is established between party members, approaching a designated teammate automatically enters that player's active quest progress." The gameplay effect is that a party member who has not personally started a quest can still contribute to its completion and receive rewards simply by being near a teammate who is running it. This is particularly useful for main story progression and world-event quests, where the normal co-op flow would require each player to hit the trigger independently.
Dynamic Reward Adjustment
Link-completed quests use dynamic reward adjustment rather than flat per-player drops. the rewards as "dynamically adjusted" (动态调整) when quests are completed in Link state, which avoids the standard gacha-MMO issue where shared quests give reduced rewards to participants who didn't personally initiate them. The exact dynamic-adjustment formula is not documented.
Party Size Interaction
The standard party cap is 4 players, but each player equips two Resonances and swaps between them in combat, which means a full party has up to 8 distinct combat styles on the field. Link interacts with party size in that any player within "nearby" range of a linked teammate benefits from the quest sharing, so a tight 4-player party can keep all four members enrolled in each other's active quest while exploring together.
Related Party Features
Link is one of several squad features that work together at launch:
Link (联动) automatic quest progress enrollment, documented here
Party marker system (组队标记) lets squad members drop world markers for coordination
One-click rally (一键召集) teleport teammates to the caller's location for instant regroup
These features are listed alongside Link in the Tencent official site but are documented as separate features, not sub-features of Link. See Party and Matchmaking for the full multiplayer stack.
Distinction From Normal Co-Op
In normal non-Link co-op, each player must personally interact with a quest NPC or trigger to register the quest in their own log. This means parties running side quests typically have to repeat triggers for each member, which wastes time. Link bypasses this friction by automatically enrolling teammates when they come close to a player who is actively running the quest. The practical effect is that Link parties can clear open-world quest content much faster than unlinked parties.
