|Charge||Phys||A powerful charge that knocks its foes over.|
|Neck Smash||Phys||If a neck is being climbed, that head will smash itself to the ground.|
|Head Strike||Phys||A head smash that stabs the ground.|
|Tail Whip||Phys||Spins around and whips its enemies with its tail. Has long reach.|
|Miasma Spit||Mag/Status||Sprays up to four long range jets of deadly Miasma, which will linger on the ground for a time. May inflict Poison. Poisoned prey will not be able to struggle when the Hydra attempts to devour them.|
Attempts to swallow a target; Arisen who fail to free themselves (wiggle the L-stick) when swallowed will die if they are not freed before reaching the main body. Pawns swallowed and not freed in time cannot be revived and must be re-hired.
Solo Arisens who fail to free themselves will die instantly and do not get to see themselves sliding down the Hydra's throat.
Solo Arisens poisoned by Miasma Spit will not be able to struggle to free themselves and will be instantly killed by being swallowed.
Striking at the head, preferably with cutting weapons may remove a head, leaving an uncontrolled stump .. searing the stumps with Fire delays regeneration.
An alternative way to destroy a Hydra head is by using a powder barrel; when thrown at the right moment, one of the Hydra's heads will swallow it. Shooting or striking the bulging throat will trigger an explosion. If done correctly, the head that swallowed the barrel will both take massive damage from the explosion and cauterize the wound to prevent regeneration.
By cutting off all four heads of the Hydra before each can regenerate, the Hydra’s body will collapse, become immobile and highly vulnerable. During this time, the party should take advantage as the Hydra will take more damage from any attack on its neck stumps, making it an easy kill. However, it will regenerate at a high speed in this state, so one should inflict as much damage as possible. A Hydra will regenerate one full health bar in the decapitated state when regenerating, whilst an Archydra will regenerate two full health bars.
The Hydra faced in the Encampment does not die when the Arisen takes its head in the early game; it flees. The Hydra can be fought later during the Post-Game in the Proving Grounds as part of the quest A Challenge. After the quest is complete, the Frontier Caverns Hydra will respawn after three days like all boss monsters.
- Weak to Fire: Permanently and temporarily fire enchanted weapons, fire-based spells, and items causing fire are effective.
- Weak to edged weapons; swords & daggers can cut off its heads.
- Attacks nearer to the head are more effective.
- After cutting off a head, setting the stump on fire will delay the regeneration of the head whilst the stump is ablaze.
- Attacking a dead stump seems to inflict more damage than attacking the other heads.
- After one of the heads initiates a "head butt" strike, the head will be temporarily at ground level - use this opportunity to decaptitate with a strong physical attack, or to mount the snake near to the neck, and then attack.
- If possible, employ the augments Adhesion (for grip), Opportunism (+30% Strength) and Arm-Strength (for Stamina) with Gloves of Might (more climbing speed) for best results.
- Striders : Splinter Dart or Fracture Dart are good skills against the Hydra, both have elemental Fire damage, a wide range of attack, and good height.
- Striders, Rangers and Assassins : Blast Arrows will damage heads as well as searing stumps with fire.
- Rangers : Hydra Husk not only does much greater damage than other longbows, but also is especially effective at severing heads.
- Magick Archer : Immolation whilst climbing exploits the Hydra's weakness, and also prevents swallowing.
- Sorcerers : Bolide and related spells are the most effective - each head acts as a separate target for the meteors.
- Mages and Sorcerers : For fun, cast a Brontide based spell and wait for a head to eat you. Canceling the spell will unleash multiple tongues of Levin's lightning into the Hydra's mouth. This may cut off the head that swallowed the Arisen. Even if it fails to cut off the head, the Hydra will spit out the Arisen.
- Mystic Knights : Great Cannon is ineffective unless Fire-enchanted; climbing attacks with Abyssal Anguish and Fire-enchanted weapons are effective; Stone Forest on a partially- or better yet, fully-decapitated Hydra does massive damage.
- Avoid the tail area. Striking the tail inflicts no damage, but tail whipping can inflict great harm to the party.
Pawn Bestiary Knowledge
- Hydra Tactics - Grants knowledge for the whole Hydra family
- Hydra Strategy Vol. 1 - Advises using a sword to sever the heads.
- Hydra Strategy Vol. 2 - Suggests searing the stump (using Fire attacks) to prevent regrowth of a severed head
- Throw an Explosive Barrel into a mouth and shoot the bulge to make it explode
- If the pawn has this knowledge, they will say "Shoot the bulge in the neck" when the Hydra swallows a barrel. Knowledgeable pawns will also shoot the bulge, if their vocation permits
- Have all 4 heads cut off at the same time
In addition to witnessing these techniques, it is necessary for Pawns to participate in killing 7 Hydras either with their own Arisen or while travelling with others.
Explosive barrel advice
Throwing an explosive barrel in the Hydra's mouth and then shooting the barrel with an arrow will decapitate a head, can be difficult to do, but is required for the Pawn Bestiary Knowledge.
To illustrate, after sufficient attacks (lightning is especially useful), a Hydra's head can be stunned, with its head swaying slightly above the ground and its mouth open for about 15 seconds. During this moment, grab an explosive barrel, walk close to the head, and throw it towards the opened mouth. The head will immediately swallow it, bulging the throat as the barrel moves slowly down the neck over about a minute and a half. During this time, attacking the bulge with an arrow will explode the barrel, tearing off the head and sealing the wound with flame.
- The simplest way to observe a barrel throw is at The Encampment during the Hydra encounter in the quest A Rude Awakening. Be sure to choose a vocation that can shoot arrows.
- When the Arisen reaches The Encampment, remove weapons from Pawns, or release them into the Rift so they are less likely to decapitate one of the four heads and complete the quest.
- Wait, observe the battle, but do not attack.
- The Hydra will eventually coil itself in front of the northern gate, and a cutscene will show Mercedes throwing an explosive barrel to the Arisen who will then toss it towards the Hydra. After the cutscene, the Arisen must shoot the barrel in the Hydra's neck.
Witnessing the 'barrel throw' at least 2 to 3 times is required for the Bestiary knowledge. The Encampment Hydra encounter can be repeated quickly by switching difficulty to Hard Mode and back (resetting the game progress but not losing character development). This is repetitious, but Mercedes' assistance in the cutscene is much easier than throwing the barrels manually when fighting the Hydra or Archydra.
NB When shooting the neck, be sure to use the "Come!" command (Down on the D-pad), to ensure pawns are close enough to witness the event and gain bestiary knowledge.
- It takes 1 minute and 40 seconds for the Hydra to slide a swallowed Arisen or pawn from mouth to main body, with the prey going through five stages as they pass down the Hydra's neck.
- During the Hydra encounter in the Encampment the soldiers are not able to free themselves, and quickly slide down the Hydra's throat.
- The Hydra in the Proving Grounds will also attempt to swallow the Goblins. Unlike the soldiers in the Encampment, Goblins have the chance to free themselves, but always fail. The swallowed Goblin will disappear immediately after the Hydra swallows it instead of sliding through its throat.
- After losing half of its health, the Hydra will take on a bloody appearance.
- The Hydra is known from ancient Greek Myths as a many headed serpent-like water monster. In the myth the hydra regrew two heads for every one cut off. It was fought by the hero Heracles, first with flaming arrows, and then with a hand weapon, in the course of the battle discovering its ability to grow many heads. Using advice to burn the stump of each severed head, he successfully defeated the monster. In another version of the story he used the Hydra's own poison to cauterize the wounded stumps.
