Description

Geminate Serpents are very long, serpent-like fey with a head at either end of their snake-like bodies. Their heads are very dragon-like, and geminate serpents can easily be mistaken for dragons if the entire creature is not seen. They earn their name for the gem-like quality of their scales. Being fey creatures they are very long- lived, growing through the entirety of their very long lives; like dragons, they have their development categorized with age classes ranging from 1 to 7.

To geminate serpents, breeding is the ultimate goal of their lives. Each lair will always include an immature geminate serpent. The adult female of this species cares for its young until they reach the second or third age class. During this time both parents will take turns hunting for food (when numbers encountered are rolled, they will be in order, Female, offspring, Male, and further offspring). If there is only a female parent present, the immature serpent will accompany their mother on her hunts. A geminate serpent will have a morale of 12 when defending its offspring, and will never leave their side, even if doing so risks its own death.

Using its long serpentine body to constrict its prey is its favorite attack; geminate serpents can carry or constrict one creature of humanoid size or less per 20 feet of its body's length. The constriction attacks of these serpents do subduing damage. When their prey falls unconscious, the geminate serpent brings them back to their lair to train their offspring to hunt. Once the prey is brought back to the lair, they are stripped of the armor, weapons, and shiny or dangerous-looking items like spell-books, which are added to the serpent’s treasure hoard. The prey are then dropped in a hole, usually as deep as half the serpent’s length. Every other day, one creature is removed from the pit as set to fight the serpent’s offspring, under the watchful supervision of the parent. If the adolescent serpent seems to be losing, the parent will intervene, either dropping them back into the pit, or killing them to feed the offspring.

Geminate serpents have a breath weapon (except bone serpents), which they may use as many times per day as they have Hit Dice. However, they may only use its breath weapon every second round. It can use a non- empowered version that does no damage (basically just fog) for obscuring cover as often as it likes. A geminate serpent’s breath weapon will only affect those equal or less hit dice to the serpent unless otherwise stated, and a saving throw is failed; creatures with more than five hit dice less than the serpent do not get a saving throw. Geminate serpents are immune to their own breath weapons, as well as all spells or poisons that replicate their effects.

Geminate serpents all speak their own language, Serpentine. They also have a chance of speaking Elvish depending on age category, as specified in the tables below for each type.

Blue geminate serpents tend to live in colder climates, often on hilltops and the like. Their scales resemble deep blue sapphires. These serpents often prey on farmers and livestock captured from the farmlands surrounding towns and cities, utilizing its breath to freeze and drag its victims back to its nest. Frozen creatures are unable to do anything besides breathe for 1d8 hours.
