ESO's 'holy trinity' of roles – Damage Dealer (DPS), Tank, and Healer – is crucial for group content. While classes are flexible, optimizing your build for a specific role will significantly improve your performance and group synergy. This section provides a high-level overview of what each role entails and key considerations for building them.

Damage Dealer (DPS):
The primary goal of a DPS is to inflict as much damage as possible on enemies. This involves optimizing your gear, skills, and rotation to maximize your damage output. DPS builds typically focus on either Magicka or Stamina as their primary resource. Magicka DPS often use staves, light armor, and spell-based abilities, while Stamina DPS use two-handed weapons, dual wield, or bows, and medium armor with weapon-based abilities. Key stats to prioritize include Weapon/Spell Damage, Critical Chance, Critical Damage, and Penetration. Resource management is also vital to maintain a consistent damage rotation. Practice your rotation on target dummies to refine your skills.
Tank:
Tanks are the frontline defenders, responsible for drawing enemy aggression (taunting), mitigating incoming damage, and controlling the battlefield. They typically wear heavy armor, use a sword and shield, and prioritize Health, Physical Resistance, and Spell Resistance. Key skills include taunts (Puncture, Inner Fire), damage shields, self-heals, and crowd control abilities. Resource management for tanks often involves balancing Stamina for blocking and dodge rolling, and Magicka for shields and utility. Understanding boss mechanics and positioning is paramount for a successful tank. Communication with your healer is also crucial.
Healer:
Healers are responsible for keeping their group alive by restoring health, providing defensive buffs, and cleansing debuffs. They typically wear light armor, use restoration staves, and prioritize Magicka as their primary resource. Key skills include single-target heals, area-of-effect heals, damage shields, and buffs like Minor/Major Courage. Resource management is critical for healers to maintain a steady flow of healing. They also often contribute to group damage with offensive spells and provide utility through synergies. Positioning is important to ensure all group members are within healing range. Understanding when to burst heal versus apply heals-over-time is a key skill.
