A gargantua is a very large variety of some normal monster. These monsters are extremely rare, the products of research of the mad wizard Gargantua. Monsters rumored to have gargantuan forms include various bugs (ant, bee, beetle, centipede, robber fly, scorpion, spider), carrion crawler, cockatrice, gargoyle, hydra, lizard man, minotaur, ogre, troll, and umber hulk. Three examples of Gargantuan creatures are given above.
Because of their incredible size, gargantuan are noisy while moving, and cannot surprise anything. They also suffer a -4 penalty to their Hit rolls when attacking mansize or smaller opponents.
The statistics for any gargantuan monster are calculated as follows:
Height: 2 times normal
Hit Dice: 8 times normal, counting each “plus” as one Hit Die added
Movement rate: 2 times normal
Damage: 4 times normal
Number Appearing: 1 (except near the Tower of Gargantua)
Save As: Fighter of equal level, 1/2 level if the monster is unintelligent
Morale: 11
Treasure Type: 4 times normal size, at 2 times normal percentages
Armor Class, Alignment, Number and type of Attacks, and normal and magical abilities are unchanged, except for regeneration (4 times normal rate). Other logical changes can be made; for example, the gargantuan carrion crawler’s tentacles are large enough to inflict damage.
Gargantuan monsters with special abilities (spells, breath weapons, etc.) are not recommended. Breath weapons, for example, would be increased in both size and damage-too-deadly an effect.

The gargantua of Mystara are extremely large and powerful specimens of other monstrous species. Such creatures horrify characters chancing upon them due to both their size and their ferocity. Those listed here are the most common forms of gargantua on Mystara. but any type of monster, creature, construct, or humanoid could have a gargantuan form, too.
Gargantua strongly resemble normal specimens of a particular monster differing only in their extreme size. For example a gargantuan troll is green and warty with a long skinny body and grimy claws, just like a regular troll. It also happens to stand approximately 20 feet tall.
Combat: In battle gargantua fight in the same manner as the normal specimens of their species. However, their great size causes them to make lots of noise while moving, so they cannot surprise anything. Gargantua that are huge (H) or larger in size also suffer a -4 penalty to their attack rolls then battling man sized (M) or smaller opponents.
Gargantuan creatures have the same number and type of attacks, Armor Class and alignment as their smaller brethren. Magical abilities likewise remain unchanged, except for regeneration (per the spell), which occurs at twice the normal rate.
Many, but not all, gargantua can swallow opponents whole on a bite attack roll of a natural 20.
Habitat/Society: The first of these creatures were the extraordinary creations of the wizard Gargantua. Such monsters have appeared across the various lands of Mystara for the past 100 years and more. It is unknown whether so Gargantus still lives in some hidden location creating even larger and stranger beings It is also unknown whether his gargantuan "children" can reproduce. although many of the most learned wizards and sages fear this is indeed the case.
Gargantua are solitary, though they may come together for mating purposes.
Ecology: Gargantua consume the same type of food as do their smaller counterparts, but they require vast numbers of calories to keep their immense bodies functioning. Their tremendous size also means they rarely live anywhere but in the most isolated of regions, only occasionally venturing into more civilized lands.
Carrion CrawlerUnlike the normal kind, the gargantuan carrion crawler does not feed solely on carrion. Instead, this monstrous creature actively hunts for meals --although anything smaller than an elephant usually avoids its notice. Like a regular carrion crawler. the gargantuan version attacks to paralyze opponents, then tries to eat them. Unlike smaller versions, the gargantuan carrion crawler can swallow man-sized or smaller opponents whole.
Gargantuan carrrion crawlers have been spotted only in the largest underground caverns in the wilds of Mystara.
