WikiIcon Research Research Required
This article/section is missing crucial information and may require additional research to answer the following questions:
  • Based on several sources, each of the Hydra's heads represents 1 figure. Is the creature considered a Icon MultiFigureUnit.png Multi-Figure Unit for all purposes other than its appearance in-game, or is it sometimes considered as a single figure?

Advisor Sorcery Buggy Feature
As of Master of Magic v1.31, Hydra is known to be malfunctioning in at least one way. Please read the Known Bugs section below.

The Hydra is a type of Fantastic Unit featured in Master of Magic. Hydras belong to the Icon Chaos.pngChaos Realm, and may be summoned using a Summoning Spell of the same name.

The Hydra's Icon Melee Normal.png Melee Attack is ferocious, and is also preceded by a powerful Icon Breath.png Breath Attack that deals Fire Damage. The Hydra has a constant Regeneration that will restore its health, and it is immune to most Curses and other combat maledictions.

The Hydra may appear to be a Icon SingleFigureUnit.png Single creature, but for (almost?) every purpose it is actually treated as a Icon MultiFigureUnit.png 9-figure unit - with each of the creature's 9 heads behaving like a separate figure. As a result, its "dry" combat values belie its true potential.

The Fantastic Unit Edit

Physical Description Edit

The Hydra is a massive reptile covered in green scales. It has 9 separate heads, each on its own neck. Each head has a mouth full of sharp teeth, and can breathe fire at its enemies. Wounds and injuries received by the Hydra will quickly congeal and begin regenerating lost bodyparts - even whole heads.

The Hydra appeared in ancient Greek mythology, where it was defeated by the great Heracles (Hercules) who cut off each head one-by-one, burning the stumps with a torch to keep them from growing back.

A "Hydra unit" contains only a single visible Hydra. However, each of the Hydra's heads is treated as a separate figure, making this a Icon MultiFigureUnit.png 9-figure unit.

Multi-Figure Creature Edit

A fully-healthy Hydra possesses 9 heads. Although it appears as only a single large creature, the unit is treated as though it is actually made up of 9 separate Icon Figure.png figures, and thus works similarly to a Icon MultiFigureUnit.png multi-figure unit.

As a result, each of the Hydra's heads will deliver its own attack, as per the rules of multi-figure Melee Damage. Furthermore, the Hydra's heads suffer injuries in sequence (with the first head receiving damage and only then, if the first head dies, the second head receives damage, and so forth).

The visual representation of the Hydra does not show how many heads are left: the Hydra will always appear to have exactly 5 heads - even if in actuality it only has one head left. The number of remaining heads is therefore clearly displayed in the unit's details panel for reference.

Attack Properties Edit

The Hydra's Melee Attack strength is Icon Melee Normal.png 6. Coupled with the creature's innate Icon ToHit.png +10% To Hit bonus, this gives an average damage output of Icon Damage.png 2.4.

Each of the Hydra's currently-living heads attack simultaneously, as though they were separate Icon Figure.png figures in a unit. Therefore, although each attack is only mildly strong, the total damage output from all 9 heads can be quite powerful. As the Hydra loses heads of course, its Melee Attack will become proportionally weaker.

Furthermore, before applying its Melee Damage, each Hydra head also makes a Breath Attack with a strength of Icon Breath.png 5, which should deliver about Icon Damage.png 1.5 points of Damage on average. This attack inflicts Fire Damage, so units with Magic Immunity and/or Fire Immunity are highly unlikely to suffer any damage from it.

Note that the Breath Attack occurs only when the Hydra is actively assaulting an enemy unit, and not when Counter Attacking to an enemy's assault.

Defensive Properties Edit

Despite its scaly skin, the Hydra is one of the least defensible Fantastic Units in the game, with a Defense score of only Icon Defense.png 4. Thus, it will block only about Icon Damage.png 1.2 points of Damage from any attack made on it.

On the other hand, the Hydra is also one of the toughest units in the game. Each head possesses Icon Hits.png 10 Hit Points, allowing the unit to sustain a total of Icon Damage.png 90 points of Damage before it is completely destroyed!

Note again that the Hydra is considered a Icon MultiFigureUnit.png Multi-Figure unit for purposes of sustaining damage - its heads will die one by one, weakening the unit's attack strength with each lost head. The number of remaining heads is clearly displayed at the top of the unit's details panel.

Finally, the Hydra possesses a Resistance score of Icon Resist.png 11 - one of the highest Resistance scores of any unit (not accounting for enchantments and other combat effects). Therefore, Curses and other combat maledictions that do not incur a Resistance penalty may not affect the Hydra at all. Such a spell or ability would need to inflict at least a Icon Resist.png -2 Resistance penalty to have any chance of affecting this unit.

Other Properties Edit

The Hydra is exceptionally slow, Walking at a pace of only Icon Movement Ground1, both on the overland map and during combat. It must struggle to close the distance with the enemy to avoid being weakened by Ranged Attacks in the interim.

Fortunately, the Hydra possesses the innate ability of Regeneration. Therefore, it will regain exactly Icon Hits.png 1 Hit Point at the end of each combat turn (i.e. each time the Hydra's army finishes its turn). If the Hydra has fewer than 9 heads remaining, and all living heads are fully-healthy, the next regained Icon Hits.png Hit Point will restore 1 head back to life - as occurs with Icon MultiFigureUnit.png Multi-Figure units. That head will now have Icon Hits.png 1 Hit Point, and additional regained health will slowly heal it until it is at full health. After that is done, the next head is restored (and the next, and so on) until the Hydra regains all 9 heads with each of them at full health.

Furthermore, thanks to Regeneration, if the Hydra's army wins the battle, the Hydra is restored to full health immediately when returning from combat to the overland map. This occurs even if the Hydra was completely destroyed during the battle!

Basic Tactics Edit

The Hydra is a veritable power-house, delivering a massive Icon Melee Normal.png Melee Attack and capable of absorbing vast quantities of Icon Damage.png Damage before being destroyed. Even if it is severely wounded, or even killed during battle, the Hydra will regain full health if its side manages to win!

This makes an army comprised entirely of Hydras almost impossible to destroy, and makes this one of the most powerful creatures in the game.

On the other hand, the Hydra is quite fragile in terms of blocking damage, which makes it vulnerable to enemy Ranged Attackers and direct-damage spells. Try to reach the enemy lines as quickly as possible, engaging as many enemies as possible before the Hydra is overcome.

Remember that the Hydra's Icon Breath.png Fire Breath attack is only used when the unit voluntarily attacks an enemy - and not when Counter Attacking. Therefore, it may be prudent to make one attack and then retreat, forcing the enemy to waste their turn closing the distance with the Hydra (if they choose to do so). Otherwise the enemy might attack the Hydra on its own terms, in which case the Breath Attack will not be used.

Also remember that enemy units with Magic Immunity and/or Fire Immunity are resistant to the Breath Attack. Of course, they may still suffer plenty of damage from the Hydra's normal Melee Attack.

Finally, if your Hydra is severely injured, consider allowing it a few turns to Regenerate. This may or may not be possible, depending on whether enemy units are actively chasing your Hydra around the battlefield. It is too slow to easily evade opponents trying to destroy it while it is weak.

Enemy Hydras Edit

Hydras are exceedingly rare as neutral creatures, and may or may not be encountered at all during an entire campaign. If they appear, they will be found in high-level Chaos Nodes or Towers of Wizardry, and are usually found alone. If not alone, they will be accompanied by any kind of lower-level Icon Chaos.pngChaos creatures.

Hydras are slow, and therefore can be attacked rather safely with Ranged Attacks to whittle them down. Unfortunately, they also Regenerate, so it is important to concentrate fire against the creature until it is dead - to prevent it from restoring its own health. Note however that a Hydra with several heads missing is significantly weaker in Melee Combat, and may be engaged by other strong units with little danger.

If possible, try to assault the Hydra during your own turn, rather than letting it attack your units. This prevents it from using its Breath Attack. This is often easier than it sounds, as the Hydra is frightfully slow and has a hard time maneuvering.

Remember that if you do not defeat the Hydra's entire army, the creature will return to life at the end of the battle. This is one of the reasons why an army made up of 8 or 9 Hydras can be virtually impossible to defeat...

Ability Overview Edit

Ability ToHit +10% To Hit Edit

  • This unit has an extra Icon ToHit.png 10% chance to hit its target with every attack. This improves its statistical chance to inflict more Icon Damage.png Damage with each attack it makes.

Ability Regeneration Regeneration Edit

  • At the end of its combat round, this unit regains Icon Hits.png 1 Hit Point, as long as it is not already at full health.
  • If the unit has one or more dead (missing) Icon Figure.png Figures, and all remaining figures are at full health, the next Icon Hits.png Hit Point will restore Icon Figure.png 1 Figure to life. Subsequent turns will see that figure regaining health until it is fully-healed, whereupon the next figure is restored to life, and so on.
  • If an army stack containing this unit wins a battle, the unit is restored to full health immediately at the end of the battle. If the unit was killed, it is restored to life and full health at the end of the battle (again, only if its army won).
  • If the unit is killed in battle, and its army retreats or is defeated, it is destroyed and will not regenerate.

Ability FireBreath Fire Breath 5 Edit

  • Whenever this unit makes a Icon Melee Normal.png Melee Attack against an enemy target, it also delivers a Fire Damage Breath Attack with a strength of Icon Breath.png 5 per Icon Figure.png Figure.
  • As a Breath Attack, this damage is delivered before the enemy gets the chance to retaliate. Any figures in the target unit that are killed by the attack do not get to deliver any Melee Damage.
  • This Breath Attack does not occur when the unit is Counter Attacking against an enemy assailant.
  • This effect does nothing against targets possessing the Magic Immunity or Fire Immunity abilities.

The Summoning Spell Edit

Usage Edit

Hydra may only be cast on the overland map, for the base Casting Cost of Icon Mana.png 650. Upon casting, the new Hydra unit will appear in the town currently containing the caster's Summoning Circle.

The new unit is created with full Movement Points, and may move and/or attack immediately as necessary.

To keep the Hydra in play, it is necessary to pay an Upkeep Cost of Icon Mana.png 14 per turn. This is drawn automatically from the caster's Mana pool each turn. Failure to pay the required costs due to lack of Icon Mana.png Mana in the pool will lead to the Hydra being immediately destroyed, along with any Unit Enchantments currently affecting it.

If the unit is destroyed in combat, then it is gone from the world entirely, and there is no further need to pay its Upkeep Costs.

You can also dismiss the Hydra voluntarily. To do this, right-click the unit's icon and then press the red "Dismiss" button on the bottom right corner of the unit's details panel. A dismissed unit is gone forever, but of course you can always cast the Hydra spell again to get a fresh new one. The primary reason to dismiss a Fantastic Creature would be to remove its Upkeep Cost (conserving Icon Mana.png Mana as a result).

Acquisition Edit

As a Very Rare Icon Chaos.pngChaos spell, Hydra may become available to any Wizard who possesses at least Icon Chaos.png3 Spellbooks. However, its availability during the game is not guaranteed unless the Wizard acquires at least Icon Chaos.png10 Spellbooks.

Hydra may not be acquired at the start of the campaign regardless of how many Spellbooks the wizard possesses. It must either be Researched during the game, or acquired through other means.

Wizards with Icon Chaos.png3 to Icon Chaos.png9 Spellbooks have a random chance of being able to Research Hydra during the game. The chance for this spell to appear for research increases with the number of Icon Chaos.pngChaos Spellbooks the Wizard possesses or obtains during gameplay. With Icon Chaos.png10 or Icon Chaos.png11 Spellbooks, the spell is guaranteed to appear for Research at some point, if it is not already available for casting.

Hydra has a base Research Cost of Icon Research.png 1,850.

With at least Icon Chaos.png3 Spellbooks, the Hydra spell may be acquired as a reward for winning encounters in creature Lairs, Towers, et cetera, or when conquering the Fortress of a rival wizard who has already researched this spell.

Known Bugs Edit

Two bugs are known to afflict the Hydra. Fortunately, neither of them is serious and they do not destabilize the game.

Mysterious Bonus Health Edit

In some circumstances, the Hydra may begin acquiring bonus health (shown as golden Icon Hits.png Heart icons) while regenerating. As it regains health, the bonus Hit Points will increase with each restored head, until the final head has Icon Hits.png 20 instead of Icon Hits.png 10. This is undocumented, there is no known reason why it should happen (given the rules of the game) and thus is most likely a bug. One reasoning for that could be the ability of the mythological hydra to regrow two heads for each that is destroyed, making it stronger the harder it is fought.  The problem with this theory however is that the same bug effects all Regenerating units with more Icon Hits.png Hit Points (per figure) than (maximum number of) Icon Figure.png Figures, which includes Shadow Demons, War Trolls and standard Troll units who gained Icon ExpLevel 3.png Elite rank.

Missing Animation Frame Edit

The Hydra's attack animation is missing one of its frames. As a result, whenever the Hydra is engaged in Melee Combat with another unit, it will visibly flicker.

Fortunately this does not have an adverse effect on the game, but can be annoying nonetheless.
