Make Use of Co-op Strategy
Assign Roles: In co-op play, clearly define the roles of Elden Ring Items each player. The tank should focus on keeping aggro, while damage dealers (such as Wylder or Recluse) should focus on staying behind the boss and dealing damage.

Stay Close to the Tank: Ranged characters should stay close enough to the tank so that the aggro remains with them, but far enough to avoid getting hit by the boss. Tanks should keep the boss in front to prevent sudden attacks on the squishy teammates.

When to Use the Tank’s Ultimate Ability
Many tank builds have a special ultimate or defensive power that they can use in key moments to draw attention or survive a critical moment. For example, the Duchess ultimate in Nightreign can be used when the tank needs a quick moment to heal, or to restore lost health in case the tank is overwhelmed.

Tank's Role When the Boss Splits or Transitions
If the boss (like Gladius, Beast of Night) splits into multiple forms, the tank’s job is to keep the aggro on all the different parts. This can be tricky, but managing the positioning and making use of the environment can help prevent confusion and keep the fight manageable.

When the boss divides into three forms, use this moment to heal, reposition, or buff your team as the tank retains aggro. It’s essential that the tank focuses on one form at a time and controls the enemies effectively.

Keep a Cool Head and Adapt
Finally, a good tank knows how to adapt. Sometimes bosses change their behavior or use new attacks that could throw off your strategy. Always be ready to switch tactics: use your mobility, stay aware of your surroundings, and maintain aggro with precise attack timings.

Conclusion:
Letting the Tanks handle aggro is key to ensuring a smooth fight and protecting your teammates in Elden Ring. Tanks need to use their defensive skills, positioning, and consistent threat generation to manage aggro. By wearing appropriate gear, using aggro-building abilities, and staying close to the boss, they can ensure that the fight remains controlled and that your damage dealers can focus on dealing damage without worrying about dying. Keep communication clear and adapt to the boss's moves, and you’ll be able to Elden Ring Runes successfully let the tank do what they do best!
