Hired Mercenaries – Permanent allies that stay with you throughout the game until dismissed.
Reinforcements – Temporary allies summoned for a short duration, usually in response to tough encounters.
Each mercenary has its own abilities, gear options, and upgrade paths that enhance their effectiveness in battle.

Hired mercenaries can be recruited in towns and act as long-term companions. These allies can be leveled up, equipped with gear, and even customized with skills.

Upgrading and Managing Mercenaries in Diablo 4
The Mercenary System in Diablo 4 introduces a significant new layer to gameplay, where players can hire powerful companions or call reinforcements to help in difficult encounters. While mercenaries can be essential for combat, their true potential is realized when you properly upgrade and manage them. This article will guide you on how to enhance your mercenaries to their maximum potential and efficiently manage them during your journey through Sanctuary.

1. Leveling Up Your Mercenaries
Leveling your mercenaries is one of the key ways to increase their combat effectiveness. As they fight alongside you, mercenaries gain experience, just like your character. Higher-level mercenaries gain access to stronger abilities, increased stats, and better combat performance.

How to Level Up Mercenaries:
Fight Together – Mercenaries gain experience from fighting enemies with you. The more enemies you kill together, the more XP they earn.
Special Missions – Some quests and special missions offer increased experience rewards for mercenaries. Completing these missions can significantly boost their level.
Bonus XP Items – Some items, such as Tomes of Experience, can be used to instantly level up mercenaries.
At higher levels, mercenaries unlock new active abilities and passive bonuses that can synergize with your class and help you in different ways, such as boosting your damage, tanking for you, or supporting your healing needs.

2. Gear Upgrading for Mercenaries
To maximize the potential of your mercenaries, you must equip them with powerful gear. This includes weapons, armor, and accessories that can significantly improve their performance in battle.

Types of Gear:
Weapons: Equip mercenaries with powerful weapons that enhance their preferred combat style (e.g., bows for Rangers, swords for Assassins, staves for Sorcerers). Weapons can increase their damage output, attack speed, and elemental effects.
Armor: Mercenaries need appropriate armor to survive in the battlefield. Tanks like Templars need heavy armor to absorb damage, while DPS mercenaries benefit from lighter armor that increases their mobility.
Jewelry (Rings, Amulets, etc.): Jewelry can provide mercenaries with critical boosts, such as increased damage resistance, enhanced critical hit chance, or increased movement speed.
Upgrading Gear:
Crafting and Forging: Gear for mercenaries can be upgraded using crafting materials found in dungeons or from enemies. Crafting can improve the rarity of gear and apply beneficial effects to increase performance.
Enchants and Runes: Gear can be further enhanced by applying special runes and enchantments that increase damage, healing, defense, or elemental resistance. These runes can be customized to fit the mercenary's role (e.g., increase a Tank's durability or a DPS merc's attack power).
3. Skill Upgrades and Synergies
Each mercenary comes with a set of skills that can be upgraded as they level up. Some mercenaries also offer synergies based on your class build, making it important to choose mercenaries that complement your playstyle.

Mercenary Abilities:
Active Abilities: These abilities allow mercenaries to deal damage, control enemies, or provide buffs and healing. For example, Rangers may unlock abilities like Poison Arrows, while Sorcerers can gain access to devastating spells like Fireball.
Passive Abilities: These offer buffs that enhance the mercenary's combat effectiveness. For example, a Templar might gain a passive ability that increases your defense or reduces incoming damage for a certain duration.
You can upgrade these skills with the help of gear, consumables, or special items that increase skill potency. Additionally, some mercenaries may unlock class-specific synergies, meaning their abilities become even more potent when paired with certain classes, such as increasing your own critical hit chance when paired with a Rogue.

4. Customizing AI Behavior
One of the unique aspects of the Mercenary System in Diablo 4 is the ability to customize their behavior. Depending on the situation, you may want your mercenaries to act in certain ways, such as focusing on healing, tanking, or dealing high damage.

Behavior Options:
Aggressive: Mercenaries focus on dealing as much damage as possible, prioritizing enemies that deal the most damage or present the biggest threat.
Defensive: Mercenaries will focus on protecting you and other allies, using abilities that enhance your survival (e.g., shield walls or healing).
Supportive: Some mercenaries will prioritize healing you or your allies, applying buffs like increased movement speed, attack damage, or resistance to debuffs.
You can toggle these behavior modes based on the difficulty of the fight and the type of enemies you face. For example, on high-difficulty dungeons or during tough world bosses, you may prefer a defensive or supportive mercenary to keep you alive, while aggressive mercenaries work well in routine mob clearing.

5. Managing Mercenaries: Dismissing and Rehiring
While mercenaries are an important part of your gameplay experience, there may come a time when you wish to dismiss or re-hire a mercenary.

When to Dismiss a Mercenary:
Switching Playstyles: You may decide to switch mercenaries to match your new class build or strategy.
Unused Mercenaries: If you are no longer using a particular mercenary, it may be beneficial to dismiss them and hire another.
Upgrading to Better Mercenaries: As you progress, you may find higher-level mercenaries that offer better synergy with your build.
How to Rehire Mercenaries:
Simply return to the Mercenary Guild or town where you originally hired them. You can rehire mercenaries for a gold cost and sometimes a small fee if they were previously dismissed.
6. Special Mercenaries and Legendary Aspects
Some mercenaries may come with Legendary Aspects that grant additional passive effects, such as damage boosts, debuff resistance, or even unique abilities. These legendary mercenaries may require you to reach certain progression milestones or complete special quests to unlock.
