How to beat Hydra in Call of Dragons

Unlocking Hydra in your alliance is a significant move!

With their high AOE damage capabilities, they can be a major asset in big-field fights.

But be warned as fighting Hydra can be a difficult task if you don’t have an understanding regarding their skill set and mechanics.


Remember, you have a maximum of 8 minutes to take Hydra down – if you fail, all your troops will be taken out, and Hydra’s health will restore to 100%. So, it’s important to utilize all your Alliance members and strategies before the time’s up not to waste time and resources.

When it comes to your attack on Hydra, make sure to choose your heroes and units wisely.

To have the greatest chance of success, inform your alliance members that you’re going for Hydra so you can have as many players as possible. The more players you bring, the more damage you’ll deal, allowing for a much smoother victory.

Have some tanks that will take the brunt of the damage, while your other players use nukers and ranged units to deal massive damage.

The giants bone Giant Bone is an Epic artifact that helps to gain more damage towards the Behemoths with the artifact skill and ATK bonus. Another essential artifact is the spirit bangle Spirit Bangle, which can remove all the debuffs and impairment effects from your legion and surrounding friendly legions. This artifact is very important as there will be debuffs occurring within the Hydra. At least 20% of the participants should have this artifact.

If you are part of the Cavalry, Mage, or Marksman gangs, we strongly recommend that you bring the spirit bangle Spirit Bengal with you. If you are chasing the Hydra around, you can use this artifact to remove the debuff within the Inner Circle and Outer Circle, so everyone will not have a poison stack.

The poisonous will inflict one stack of poison on all Legions who take damage. Therefore, having the Spirit Bengal is essential as it helps to remove the debuff.

Upon your fight with Hydra, there are two separate mana stones that can be found dropped on the ground – the red one has a timer, while the green one has charges.

  • Red stone: If left ignored, its timer runs out, placing a debuff on both you and your alliance members, increasing the damage you take.
    These debuffs are stackable, meaning if there’s a lot of game time left, the damage you will take can become fatal. When players pick up the red stone, they themselves receive the debuff but benefit from a 25% boost in damage. It’s best to pick them up right away to ensure neither the team nor you receive a negative debuff.
  • Greenstone: It has 10 charges. It is important to grab it, as it not only gives you a heal on your troops but it removes all of the debuffs as well. If your team is low on troops or you have a lot of debuffs, make sure to collect the Greenstone.

When fighting the Hydra, it’s important to work together with your alliance and communicate effectively. Capturing the Dispelling Mana Stone requires ten players to gather, so it’s important to coordinate with your team to ensure that everyone is working together towards a common goal. Remember to grab the stone as soon as you see it, and communicate with your team to ensure that everyone is aware of its importance.

Agony Blast Agony Blast, a Hydra skill, deals AOE damage. Unfortunately, this damage isn’t avoid-able.

To minimize its effect, acquire the red stone so that your troops receive attack-enhancing buffs and the green stone if they’re on low health or have the debuff. Doing so will ensure your team takes only normal damage, rather than a really huge amount.

Poisonous Crevices Poisonous Crevices are a challenge you’ll want to be sure to keep on top of.

These circular cracks in the ground can cause a lot of havoc if they go off – all allies will take damage and extra stacks of damage debuff, so it’s important to counter them.

To do this, stand directly on top of the cracks – this will stop it from bursting, and no one will get hurt. Make sure everyone on your team is standing on each crack in the ground because everyone that gets triggered increases the amount of damage taken.

Flee if you spot a tremendous Big Red Attack from Hydra. If you stay, you’ll take enormous harm and perish.
