The Mage class has always been a popular choice for many players in Diablo IV. Mage players love casting spells, experimenting with different builds, and exploring powerful Diablo 4 Items . There are many builds for this class, but the 5-health Hydra build is by far the most unique and dangerous. This build focuses on keeping the character's health very low, then utilizing defensive strategies, particularly mana shield, to maintain near-invulnerability while unleashing the Hydra's powerful abilities.

The main ability of this build is the Hydra, a fire-breathing beast. The Hydra has long been a valuable companion to mages, capable of dealing damage without the player's attention. With this build, the Hydra is no longer just a support hero, but the undisputed protagonist. By focusing on abilities and items that increase the Hydra's durability, damage, and attack count, you can create an automated damage machine. 

The "5 health" strategy can be difficult for new players to grasp, but it's core to the genre. Diablo IV's mechanics allow players to expend resources to protect themselves. By converting mana into a shield that absorbs damage, mages can maintain their health and avoid premature death. This is where mana shield becomes crucial.

The Abyss, known for its increasing difficulty, is the final dungeon in Diablo IV. Enemies there are stronger, more resilient, and more vulnerable to attacking weaker classes. Surprisingly, the Hydra Mage, with 5 health, performs well in this environment because its survivability isn't reliant on health. As long as you generate enough mana through possession regeneration, spell management, and smart casting, the shield remains strong, making the mage a powerful tank.

This build requires skill to master. Positioning is crucial, and the mage must carefully manage their shield to avoid overextending their mana pool. However, if executed correctly, this build offers two unique advantages. With only 5 health points, this fragile mage is harder to kill than most tanks. Meanwhile, the Hydra constantly boosts enemy attacks, freeing the mage to focus on defense.

Items that reduce mana cost, restore mana, and generate shields are essential. Items that increase the number of Hydras or increase their damage while shields are active also complete the build. Essential and unique diablo 4 buy items further enhance the Hydra's damage, making each Hydra a powerful offensive weapon and making it easier to defeat bosses and those in the Abyss.
