Hydra

From beneath the seas, Teleria's most terrifying monster has been uncovered - the Hydra. You must join forces with your Clan if you wish to stand any hope of defeating the Hydra and claiming the treasures it protects.

Defeat the Hydra to claim Hydra chests containing Artifacts that can only be found here. Prove your worth by defeating the Hydra on higher difficulties for the best rewards.

The Hydra has 6 Heads, but you only fight 4 at once - starting with 4 Starter Heads. If you chop off a Head, another will grow back. It may be the same Head, or one of the other available Heads - so be prepared.

You need Hydra Keys to battle, and you have a limited number of Keys each week. Each Champion can only fight the Hydra once per week. From here, you must discover the mysteries of the Hydra alone. Good luck.

Strategy

How It Works

  1. Head of Blight

    The Head of Blight uses vast amounts of Poison to inflict damage, and brings a unique buff, Poison Cloud, to protect itself and its allies. The Poison Cloud buff causes all incoming attacks to deliver Weak Hits, which deal less damage and can’t place debuffs. If a Head with Poison Cloud also has HP Burn, all hits against it go back to normal.

  2. The Head of Blight’s other attacks focus on putting out and exploiting Poison and Leech debuffs, creating a deadly combo that can detonate tons of Poison on your Champions.

  3. This nasty combo can be easy enough to stop - blocking or removing debuffs will protect you from this Head’s worst attacks. So, it comes down to dealing damage to it, and for that you’ll want Champions with area-of-effect HP Burn. HP Burn deals bonus damage to the Head of Blight, and it neutralizes the Poison Cloud buff on all the Heads. It will also add an extra kick at the end: the Head of Blight’s decapitation effect deals damage to any Heads that are under a HP Burn debuff.

  4. Head of Torment

    The Head of Torment is focused on using Fear and True Fear to control your Champions and reset their cooldowns, but it also can deal a lot of damage if you’re not careful.

    Its attacks put Fear and True Fear debuffs on your Champions, then exploits them to deal additional damage.

  5. The Head of Torment's Passive is the real issue, though, as any Champion who attacks the Head of Torment without Perfect Veil buffs will get a True Fear debuff that can't be blocked or resisted.

    The solution is pretty clear: bring Champions who can cast Perfect Veil buffs, and Champions that can remove Debuffs. This will keep your Champions able to fight, and minimize the Head of Torment's ability to inflict damage on your team.

  6. Head of Mischief

    The Head of Mischief will attack the Champion with the most buffs, stealing them along with part of the target's Turn Meter. Then, its second Skill passes its buffs along to the other Heads.

  7. What makes this Head difficult to attack is that it has a Passive skill which redirects single target attacks to another Head. If you want to get around this, use the Hex debuff - which disables the effect - or just hit it with area attacks.

  8. You can also use the Block Buffs debuff on it to prevent it from benefiting from any Buffs it steals, and high Resistance will prevent the loss of your buffs in the first place.

  9. Head of Wrath

    The Head of Wrath is a furious damage dealer. It uses Provoke to force you to attack it, but once it takes enough punishment it will unleash a powerful buff, Vengeance, to quadruple its attack power and wreak havoc on your team.

    Attacking the Head of Wrath with lots of hits will build up stacks of the Head’s Vengeance counter. When it gets to 15, it gives itself the unique Vengeance buff and attacks your entire team with quadruple the damage. Vengeance only lasts 1 turn, but it means the Head of Wrath ’s next attack will also hit with the same devastating power.

  10. Because it concentrates so much damage into such a short time, it’s not enough to bring strong healing. You’ll need to increase the durability of your Champions with Increase DEF, Strengthen, and Shield buffs. Or, if you can carefully control the number of hits you land, you can also time your Champions to use Block Damage or Unkillable buffs right when Vengeance comes out.

    That timing will serve you twice-over, actually. Killing the Head of Wrath while it’s under a Vengeance buff doubles the damage it deals to all other Heads, and has a chance of placing Leech debuff on them.

  11. Head of Decay

    The Head of Decay will disrupt your healing and try to preserve other Heads by using a special buff: Life Barrier.

  12. The Head of Decay’s third skill removes all debuffs from the most injured Head, then gives it a Life Barrier buff. Life Barrier works a bit like Shield, but it can’t be bypassed or stolen. If you break it before it runs out, the Head is Stunned for a turn. If not, the Head will be fully healed instead.

    But the Head of Decay gets its name from its passive most of all: every time your Champions are healed, it destroys the HP of the healed Champion - the amount destroyed is equal to 15% of the total value of the heal, so putting a huge heal on a Champion that was barely injured can destroy more HP than it recovers!

  13. So, while the Head of Decay is very annoying, it doesn’t actually have a good means of defending itself. It's very difficult to go completely without healing, so you’re better off decapitating the Head of Decay as soon as possible. This also helps counteract some of the problem, since its decapitation effect heals your Champions a bit then restores 50% of the HP that its passive destroyed.

  14. Head of Suffering

    The Head of Suffering's main role is to protect other Heads, increase their Resistance, and decrease received damage. It is also eager to punish you if you neglect debuffs, as it brings the powerful Pain Link debuff to the field.

    Any Champions with a Pain Link will also receive 15% of the damage that the Head of Suffering takes. The Head still takes full damage, but your Champions aren’t nearly as durable. You can easily end up defeating your own team.

    Despite everything, there are ways to beat this Head. To help survive, you can block the Weaken it puts out with its default attack by using the Strengthen buff.

  15. Or, you can cleanse it - you’ll want to be able to remove debuffs on your Champions anyway, to deal with the Pain Link. You’ll need high accuracy if you want to remove the Head’s Reflect Damage buff, but if you do it makes things easier for your damage-dealers. And while it’s nice that the Head’s decapitation effect gives you a Shield buff, the real benefit is that the Head won’t be around to increase it’s ally’s Resistance and decrease your AoE damage.

  16. If all Heads have been decapitated, the next respawn will see 2 Heads join the battle but only one of them will receive a Serpent's Will buff. Up to 3 Serpent's Will buffs can be present simultaneously in a battle.

Poison Cloud Buff

The Poison Cloud buff blocks damage from Poison debuffs. Also, enemies can only land weak hits on Champions under a Poison Cloud buff.

If a Champion receives an HP Burn debuff before a Poison Cloud buff is applied, then the effects of Poison Cloud won't work, but the buff itself will not be removed. It's not affected by the Spread Buff and Increase Buff Duration effects.

HP Burn Debuff

When a Champion under a HP Burn debuff starts their turn, they and all their allies take damage equal to 3% of their individual MAX HP. There can only be one HP Burn debuff active on a Champion at a time.

Poison Debuff

Damages the target Champion by 2,5% or 5% of their MAX HP at the beginning of their Turn. This damage is not affected by any other effects except Poison Sensitivity debuff, and only scales per Target’s MAX HP. Block Damage blocks it. If the Target Champion has a Shield, Poison damage will be applied to the Shield first.

Leech Debuff

Any Champion that attacks a Champion with Leech debuff heals for 18% of inflicted damage.

Fear Debuff

There are two versions of this debuff: Fear and True Fear.

When a Champion with Fear Debuff attempts to use a skill, there is a 50% chance that the skill will not activate, and the Champion will lose their turn.

When a Champion with True Fear debuff attempts to use a skill, there is a 50% chance that the skill will not activate, and the Champion will lose their turn. The skill they attempted to use will go on cooldown.

Veil Buff

There are two versions of this buff: Veil and Perfect Veil. The Champion under either of these buffs cannot be targeted by the enemy.

If all remaining Champions on a team have an active Veil or Perfect Veil buff, the enemy will not be restricted in targeting a specific Champion.

Veil buffs will be removed when the affected Champion uses an active skill, but Perfect Veil buffs will not be removed. Also, Veil and Perfect Veil buffs decrease incoming damage from area-of-effect skills. Veil reduces incoming damage by 7.5%, and Perfect Veil reduces incoming damage by 15%.

Finally, Veil and Perfect Veil buffs cannot be stolen by an enemy Champion with a skill that allows them to steal buffs.

Hex Debuff

Champions under Hex debuffs take damage whenever their allies do. The damage from Hex debuffs ignores Champions' DEF. The original targets all take full damage.

Champions under Hex debuffs take 2% of AoE damage inflicted on their allies, and 10% of single-target damage inflicted on their allies.

Champions under Hex debuffs only take extra damage from direct attacks on their allies, not lasting effects (like buffs or debuffs) - for example, damage from Poison, HP Burn, Bomb debuffs, Reflect Damage buffs, etc.

Block Buffs Debuff

All buffs that are applied to the Champion with this debuff are automatically blocked and have no effect.

Increase DEF Buff

Increases the Champion’s Battle DEF by 30% or 60%.

Strengthen Buff

Reduces the value of the received damage by 15% or 25%.

Shield Buff

The Champion's HP bar is reinforced with a Shield for the indicated number of turns. Damage is calculated as normal but is first applied to the Shield (unless the attack is stated to ignore Shields). When the Shield buff expires, or the value of the Shield reaches 0, the buff is removed and any further damage is applied as normal.

Block Damage Buff

Makes the Champion immune to all forms of damage. Its duration cannot be increased.

Unkillable Buff

The Champion cannot fall below 1 HP when the Unkillable buff is active. Its duration cannot be increased.

Life Barrier Buff

Life Barrier is a buff that grants the recipient additional HP beyond their MAX HP. It cannot be removed, stolen, or have its duration increased or decreased. Skills that scale damage based on a Shield's value will count the Life Barrier buff as a Shield.

Life Barrier has the highest priority of any buff, and will be placed on top of effects such as Digestion. In order to remove effects such as Digestion, the Life Barrier must first be removed by damage.

If the Life Barrier is not removed when its duration ends, the Hydra Head's HP will be fully restored. Removing the Life Barrier will place a Stun debuff on the Hydra Head for 1 turn.

Pain Link Debuff

The Pain Link debuff causes the affected Champion to receive a percentage of all damage received by the enemy who placed this debuff. The enemy receives 100% of the damage inflicted to them.

The amount of damage received depends on the enemy who placed the debuff. If it was the Head of Suffering, then the Pain Link debuff causes the affected Champion to receive 15% of all damage received. If the Pain Link debuff was placed by a Champion, the damage received will be specified in that Champion's skill description. If it is not specified, it will cause the affected Champion to receive 15% of all damage received by the Champion who placed the debuff.

The Pain Link debuff can be blocked or removed, and can have its duration increased or decreased. Receiving a Pain Link debuff will awaken Champions under a Sleep debuff.

If a Champion is under both a Pain Link debuff and a Block Damage buff, they won't receive any damage from the Pain Link debuff.

A Champion under a Pain Link debuff won't receive any damage from it when the enemy who placed the debuff receives a weak hit.

Weaken Debuff

Increases damage received by the Target Champion by 15% or 25%.

Reflect Damage Buff

The attacker will take back 15% or 30% of the damage dealt.
