Just as the great hydra grows from the severed head of the original Lernaean Hydra, the lesser hydra grows from the severed head  of a greater hydra. While the greater hydra feels constant pangs of separation from the original, a lesser hydra has no recollection of that great, perfect whole.

A lesser hydra is far less poisonous and far less dangerous than the greater. While it is also less intelligent, it is more independent. When the head of a greater hydra is severed, the head will spout small legs, fins or tentacles in order to make its escape while the attacker is occupied with the two new heads growing in its place.

This head will then seek shelter and begin its week-long transformation into a hydra body about 3 meters long. The body shape is determined by the means the head took to escape. It could have a tail, tentacles, legs, fins or perhaps even wings. In most cases, the head will seek the nearest safe spot. During this week of transformation, it is extremely vulnerable to attack and can be treated as a 1HP mass of meat. Once the transformation is complete, 1d6 necks and heads will sprout.

The lesser hydra is usually dominated by its progenitor. The greater hydra can send simple telepathic commands to the lesser, provided they are about a mile apart or less. The slave hydra can send back simple answers such as “alarm” or “food” or images. The lesser hydra is somewhat disloyal. If it has a reasonable chance of escaping this one mile radius without being caught, it will try. Should the greater hydra wish, it can kill the lesser with a thought within that mile radius.

Lesser hydra are often posted on guard duty or sent hunting for food, for a greater hydra is a very hungry animal. When alone, a lesser hydra will seek a home anywhere it can find one. They are very vicious and still exude the poison that is the hydra’s nature. Much like other hydra, any head that is severed is replaced by two more unless fire or acid is used to cauterize the stump of the neck. For a lesser hydra, this means using a full flask of oil or acid. The severed head will attempt to escape, growing any needed appendages to do so while the attackers are distracted. Within 3 days the head will now be the body of a dwarf hydra.

Lesser hydra can spit poison as a cobra and have a poisonous bite. Some (30%) can breathe a poisonous cloud (save or take 1d4 HP/round until cured) once per day. Their blood is an effective poison if ingested and can corrode or eat through non-magical armor, weapons and other materials in a period of hours. Its blood is a much sought-after ingredient in witches’ brews and blasphemous rituals.

This is the first in a series of posts about monsters. I want to reinvent and retool some of them, while others I hope can be returned to their classical roots in literature and folklore. By making some changes, maybe we can make some old monsters interesting again, or at least surprising.

I’m going to start with several monsters from the Greek myths. Some of these, such as the hydra and Medusa, were nerfed and commoditized for D&D. First up is the hydra.

Gustave Moreau's Heracles and the Lernaean Hydra

The Hydra

In the original Greek tales of the labors of Heracles, the Hydra of Lerna was a giant, multi-headed serpent representing the hopeless battle. A strong poison ran through its veins, and if a challenger cut off one of its heads, two more grew back in its place. According to legend, it was the son of the monsters Typhon and Echidna, and among its siblings were Cerberus, the Chimera and the Sphinx. These were major league monsters, not your garden-variety beasts.  It took a demigod to defeat it and even then, Heracles needed help to do it.

But having only one official hydra makes it unlikely that players will ever see one. So let’s say the hydra of Lerna spawns smaller a smaller hydra when it loses a head. If you ever saw John Carpenter’s The Thing, you remember the scene where the Thing is under attack while still mostly in human form. The head detaches itself, sprouts legs and walks away. Let’s say that the smaller hydrae come from severed heads of the original. These heads burrow, slither or otherwise try to escape rather than attack. These heads would be very vulnerable until they grow into the body of a smaller hydra. If that hydra could in turn also spawn smaller hydrae when their heads are severed, we have the option of creating smaller and smaller hydra.

Perhaps there’s some form of psychic link between the child hydrae and their parent. The new, smaller hydra will remember what the spawning head experienced, perhaps even seeking out an enemy for revenge. Hydra might retain a telepathic link with the hydra from which is spawned in combat, and can be commanded by its “parent” when within one mile. I’d also want to make the original hydra able to send out a telepathic message to all living hydrae of any size.

All hydrae should be poisonous. The smaller varieties might have only a poison bite, while the larger ones might have a breath weapon and a permanent cloud of poisonous gas around it. The big kahuna should have poisonous/acidic blood. One note on poison: I don’t usually go for the save-or-die poisons. I like to give lots of damage, even over an extended period of time, but I don’t do save-or-die. That’s just how I roll.

The heads of a Hydra can be cut or bashed off, but care must be taken to burn the stump within 2 rounds. On the third combat round, the two new heads will have finished growing. The new heads are stuck together on one stump for the next few days, until the neck splits and allows them to be separate.

Morale 12

Hoard Class: DM Discretion

This is the original Hydra of Greek legend. It appears as a multi-headed snake, although in some accounts it has legs and the body of a reptile. It’s body is immortal and unkillable, as is one of its eldest head. Heracles himself could do no more to this last head than wedge it between some rocks after killing the other heads (and cauterizing the neck wounds).

The DM will need to decide how many heads it has and how intelligent it is. If it is weak from a recent defeat, then it will have little treasure and perhaps is not that smart. If it is strong and has faced many foolish mortals, then it will have more heads (Heracles fought nine), more intelligence and a larger number of dead bodies (and treasure) around it.

A severed head of the Lernean Hydra will immediately seek to escape into the sea, burrow into the earth or otherwise escape or hide. Within 2 weeks it will grow into a Greater Hydra. This Hydra will forever hate and seek revenge on whomever cleaved it and his or her heirs and loved ones.

The Lernaean Hydra will not tolerate the presence of another hydra on its island unless it needs to as part of a scheme or a desperate situation. It can, however, telepathically contact any other hydra within 100 leagues. It can send a short (up to 1 minute) one-way telepathic communication to all hydrae anywhere once per day. It almost never does this.

The longer a blade has been near the Lernaean Hydra, the more likely it is to have a permanently poisonous or acid dripping blade. The Lernaean Hydra’s poison is the poison from which all venoms have come. It is not negated by magic. Some assassins worship this hydra for its gift of poison to the world.

The Lernaean Hydra takes its name from the island of Lerna, where it supposedly lived. It eats entire schools of large fish, whales and other large sea beasts, but it does not need to eat often. No one is quite sure whether the separate heads are separate minds or part of one mind.

If this version of the Hydra seems unbeatable in ODD/Basic/LL/S&W terms, then I’ve done my job right. As with all things I post, please feel free to tinker, playtest and let me know what you think.

Greater Hydra to follow.
