Hydrae are reptilian monsters found in marshes, swamps, and similar places, as well as in subterranean lairs.

Their large, four-legged bodies are surmounted by from 5 to 16 heads (roll an d12 to determine number). <4+d12> <revised according to the DMG>
Each head has 1 HD of a full 8 HP.

When all of a hydra's heads are killed, the body dies, but not until each and every head is killed.

The hydra attacks according to the number of heads it has, each head being considered as a hit die.
Thus, a hydra of 7 heads attacks as a monster of 7 hit dice.

Damage scored is based on the number of heads the hydra has: hydrae of 5 or 6 heads do 1-6 hit points of damage/attack, those with 7 to 10 heads score 1-8 points of damage, and hydrae with 11 or 12 heads do 1-10 hit points of damage. <edit>

Multi-attack: It is possible for the hydra to attack several opponents at once, and up to 4 heads are able to attack the same target simultaneously.

Description: Hydrae are gray-brown to blackish brown with lighter underbellies tinged towards yellow or tan.
Their eyes are amber to orange.
The teeth are yellowish-white.

<note: DMG, discrepancies in THACOs, leave as is, uncorrected, one rule (of mortal make) does not fit all ...>

Q: What is the proper way to handle a
fight with a hydra? Does the creature
?s effective hit dice drop as it
loses heads? Will damage to the
creature?s body kill it? How do areaeffect
spells such as fireball effect
the heads? How does one determine
when a lernaean hydra?s regeneration
ability is stopped?
A: Hydras do pose a few problems, especially
when magic is involved. I suggest the
following rules for handling combat with a
hydra.
A hydra?s effective hit dice do not drop
as the creature loses heads. With respect
to melee, each of a hydra?s heads is treated
as a separate creature. Each head dies
when it reaches zero hit points, and excess
damage does not carry over to another
head. When all heads are reduced to zero
hit points, the creature dies immediately.
Hits to a hydra?s body will kill it; the body
has as many hit points as the total hit
points of its starting heads. When the
body is reduced to zero hit points, however,
the creature continues to fight as
long as it has at least one living head. It
will then fight for an additional 2-8 rounds
or until the body is reduced to -20 hp.
A lernaean hydra?s regeneration ability
makes it a tougher nut to crack. The individual
heads can be slain in the normal
manner; however, a fire source must be
applied to each slain head or it will regenerate.
Burning hands is the easiest way to
scorch the stumps or sundered heads. A
torch, flask of oil,. or flame tongue sword
will stop a single head?s regeneration if
applied in time. Any successful hit on the
slain head will stop regeneration. A lernaean
hydra stays alive as long as it has
one living or regenerating head (hits to the
creature?s body not withstanding).
When any hydra is affected by an area
spell such as fireball or lightning bolt, the
heads are treated as a single entities, with
the damage distributed as evenly as possible
among the heads. Although the heads
are separate melee targets, they are still
part of the same creature. The creature?s
body suffers as much damage as the heads
took in total (i.e., the hydra gets one saving
throw, but the heads and the body each
take damage).
Spells that can kill a creature outright
such as death spell, power word kill, or
disintegrate kill the creature only if it fails
its saving throw (if applicable). When
determining a hydra?s resistance to such
spells, its effective hit dice are equal to its
starting number of heads (or peak number,
in the case of a lernaean hydra), and
its effective hit points are equal to the total
hit points of all the heads (damage to the
body notwithstanding).
A spell that affects one creature or a
limited area (such as magic missile or
burning hands) must be directed either at
the body or at one or more heads of the
hydra, according to the limitations of the
spell. Spells such as charm monster, hold
monster; or slow affect the entire creature,
as the beast effectively has only one
brain?perhaps at the base of the necks
inside the body.

Lernaean Hydra:

Lernaean Hydra: Roll d12

1 =5-headed Lernaean Hydra	2 =6-headed Lernaean Hydra	3 =7-headed Lernaean Hydra	4 =8-headed Lernaean Hydra
5 =9-headed Lernaean Hydra	6 =10-headed Lernaean Hydra	7 =11-headed Lernaean Hydra	8 =12-headed Lernaean Hydra
9 =13-headed Lernaean Hydra	10 =14-headed Lernaean Hydra	11 =15-headed Lernaean Hydra	12 =16-headed Lernaean Hydra

These creatures are very rare.
The lernaean hydra is indistinguishable from a normal hydra until it is attacked. <DMG.230? : edit?>

Every time one <1> of the heads of these creatures is cut off or killed, it grows two <2> new ones in 1-4 melee rounds unless fire is applied to the dead member or neck stump.
    Thus, a 5-headed lernaean hydra could grow to a 12-headed monster in a single combat, gaining the appropriate hit dice and attack potential in the process.

** (if decapitation at seg1, then regrowth at a seg2 ; if decapitation at seg2, then regrowth at a seg3, etc.)

<"    They seldom exceed 7 heads, 10% having 8, and no 9-headed pyrohydra has ever been recorded. ">
    therefore, not d8 ... revise as a d% (theory .... 1=01-05, 2=06-10, 3=11-15, 4=16-60, 5=61-70, 6=71-80, 7=81-90, 8=91-00)

Pyrohydrae also appear quite similar to normal hydrae, although their coloration may be tinged with more red.
They seldom exceed 7 heads, 10% having 8, and no 9-headed pyrohydra has ever been recorded. <x>
Each head of a pyrohydra is able to breathe fire twice per day,
the breath shooting out in a cone 1/2" diameter at the mouth, 1" diameter
at the end, and 2" long. This fire causes 8 hit points of damage (4 if saving
throw versus dragon breath is made). They can, of course, strike normally
as well.
