Olhydra appears only near water as a watery amorphous blob 20' in diameter.
She attacks as a 20 hit dice monster once per round with a water wave which inflicts 2-24 points of damage. <edit>

Drowning: She can also attack by enveloping and drowning victims;
up to five <5> human-sized <(size M)> creatures may be attacked and enveloped at one time, <cf. DMG.63, for other sizes>
and are powerless to do anything (fight, CAST spells) while enveloped.
All defenders are considered armour class <AC> 6 against this attack (with appropriate magical and dexterity modifiers).
Victims drown in 2-8 rounds and take 2-12 hit points of damage each round in any case.
The only way to save enveloped victims is to kill or drive away the Princess <caps> since she cannot move enveloped bodies.
<note: the Drowning ability could be revised with the Hold Breath rules, in the WSG>

As Princess <caps> of evil water creatures,
Olhydra may summon one <1> of the following groups once per day <1 per day>:
    1-3 water elementals,
    1-2 sea hags,
    2-5 water weirds
    or 20-200 sahuagin (salt water only).

She can also perform the following thrice per day : <3 per day><each?><CL=20?>
    produce a triple-strength <(x3)> [wall of fog],
    lower and
    [part water] (at 20th level),
    [transmute rock to mud], <druidic?>
    [ice storm]. <perhaps replace ice storm with another water spell, as Olhydra is not from the Para-Elemental Plane of Ice>

Fire attacks are at +2 hit probability against her and do an additional 1 point of damage per attack die.
Cold attacks cannot damage her,
but if over 20 points in value,
they act as a [slow] spell upon her (her magic resistance is ineffective in this case, nor does she get a saving throw).
Any normal fire within 10' of Olhydra is automatically extinguished.
She cannot be paralysed or turned to stone. <edit>

Olhydra lives in a great undersea castle on the Elemental Plane of Water.
There is great enmity between her and Imix.
 

Archomentals: There is a number of powerful elementals
who are given ranks such as barons, masters, and grandmasters
by those who study such things. In physical stats most are similar
to the "Princess of Elemental Evil," Olhydra (described in the FIEND FOLIO tome), <>
though all archomentals have their own desires and motives.

    Olhydra makes her home in the ruins of a great undersea citadel
of black coral that was once the capital of a world-spanning
empire long ago destroyed by Olhydra. This might be exaggeration
laid upon by the passage of years, but the fact remains that
the lair of Olhydra is richly lardered. Would-be robbers are
warned that a dozen water elementals of max. HP and
magickal abilities serve as her bodyguard in court. Like all archomentals,
Olhydra has the powers afforded a Demi-Deity.
