**Diablo IV Game Guide**

**Server and Connectivity**
In **Diablo IV**, player data is stored on Battle.net servers, requiring a constant connection throughout gameplay. Despite Battle.net’s regional divisions—such as Asia, Europe, and America—Diablo IV’s servers are globally connected. This means players can team up with friends regardless of their country of registration.

Currently, the Asian server for Diablo IV is not available in mainland China. For a smooth gameplay experience, consider using a reliable VPN.

**Gameplay Overview**

**1. Core Mechanics**
Diablo IV retains much of the gameplay from previous installments. It’s easy for newcomers to pick up. The game features four difficulty levels, with towns and world maps being public areas. Players do not need to be in a party to gain experience or loot from these public zones. However, dungeons remain either personal or team-based.

**2. Main Quests**
- **Battle.net Account Requirement**: Completing main quests is essential for unlocking certain strongholds and features. After finishing all main quests with a Battle.net character, subsequent characters can skip these quests.
- **Expression Management**: Diablo IV introduces expression management, accessible by pressing E in-game. This feature includes various expressions and tasks that require normal emotional responses for certain game prompts.

**3. Wild Treasure Hunting**
- **Exploration**: The world map is a public area with dynamic levels, allowing players to explore any region regardless of their level.
- **Events and Rewards**: Monsters respawn quickly, and there are diverse world events, including world bosses, demon invasions, and other activities. Players in the same area can share event rewards without needing to form a team. If you participate in the same area event with other players, you’ll still receive a share of the loot, even if you don’t directly engage in all events.
- **Silent Treasure Chests**: These chests require a Whispering Key, obtained from the gambler using Whispering Ancient Coins, to open. The loot is affected by the map’s difficulty. It's advisable to wait until you're at a higher difficulty before opening these chests.

**4. World Quests**
- **Unlocking World Quests**: To access world quests, complete all main quests with your first Battle.net character. Subsequent characters can participate without restrictions.
- **World Tree and Rewards**: In Chapter 5, interact with the world tree, which offers rewards in exchange for following its guidance. World quests reward players with Terror Favor points, which accumulate to unlock additional rewards. Collecting 10 points of Terror Favor grants access to treasure chests, which can include dark gold rewards.

**5. Dungeons**
- **Types of Dungeons**: The game features over 100 ordinary dungeons, one large dungeon (Fallen Temple), numerous plot dungeons, and many caves. The difficulty and loot are determined by the chosen game difficulty.
- **Legendary Powers**: Clearing ordinary dungeons unlocks legendary powers used to craft legendary equipment.

**6. Nightmare Dungeons (Great Secret Realms)**
- **Eligibility**: Available from level 50 onwards.
- **Nightmare Talismans**: The difficulty and loot of these dungeons are based on the level of the Nightmare Talisman (Great Secret Realm Key). Primary talismans are obtainable through world quests, while advanced ones are acquired through dungeon runs. Low-level talismans can be converted into advanced ones using the illusionist.
- **Activation**: To access a Nightmare Dungeon, click the talisman in your inventory and activate the corresponding dungeon mode. Players must enter the dungeon manually.
