Homebrew Gemstone Half-Dragon Species Details
Gemstone Dragons are typically very careful to avoid these relationships in order to keep balance, with the exception of Amethyst Dragons, who seemingly have offspring for sport, often abandoning them. Topaz is the second most common half-dragon, though their draconic parent is usually absent or oblivious to the fact they have children. Emeralds stay close to the sea and the coasts, typically keeping to themselves but on occasion they befriend those living close to them. When they do, they usually devote themselves to their family until they pass naturally. Ruby Dragons, being slow to trust, typically only have half-dragon children to secure alliances and form treaties. Sapphire Dragons almost never have mortal children, when they do their children are raised and trained to fill very specific roles in society.
Gemstone Half-Dragon Traits
Your draconic heritage manifests in a variety of traits you share with other Gemstone Half-Dragons.Mindspeach
All gemstone half-dragons develop telepathy as they get stronger. At 3rd level you gain telepathy to a range of 120ft, to any intelligent creature within range. They don’t need to share a language with you to understand you but they do need to know a language.
Psionics
Crystal Hide
Normal weapons bounce and spark off the crystals extruding from a gemstone dragon’s skin. When you aren’t wearing armor, your AC is 13 + your Dexterity modifier. You can use your natural armor to determine your AC if the armor you wear would leave you with a lower AC. A shield’s benefits apply as normal while you use your natural armor. At 11th level you gain resistance to lightning and fire damage.
Sympathetic Vibrations
Gemstone half-dragons are vulnerable to psychic damage. The same crystalline structure that makes them hard to damage with normal weapons natively conducts any psionic radiation, causing its latticework to crack and shatter.
Fracture Score
Each time you take more damage than your fracture score from a single attack, spell or effect, your crystalline form fractures, diminishing your ability to recharge psionic power. Roll the recharge die and reduce your maximum charges by the result. This damage heals itself upon finishing a long rest. Your fracture score is twice the number of charges you have. You have a number of charges equal to your level, once used they refresh when you finish a long rest.
Manifestations
Psionic charges are used to manifest psionic abilities. Manifestations are the primary source of a gemstone half-dragon’s power. The crystals that grow on and thread through your body forms a network of psionic filaments that capture, conduct, amplify, and store charges of psionic energies, which you can then convert into manifestations. You can expend these charges to cast any psionic manifestation. Many of these manifestations have a base cost and can be enhanced by expending more charges. The DC for your Manifestations saving throws equals 8 + your intelligence modifier + your proficiency bonus. Work with your DM to determine which manifestations your character knows as well as if, when and how you learn more.
