A serpent is a dragon who focuses upon the mystical power inherent to dragons. While all dragons eventually develop some magical abilities related to their lineage, a serpent is a true spellcaster.
Spellcasting
At 3rd level, your draconic power manifests as innate spellcasting. Many sorcerers in the world claim to have the blood of dragons in their veins, and you are proof of that power. While a sorcerer’s power grows faster than yours, yours is in addition to your formidable draconic armaments.
Cantrips: You learn two cantrips of your choice from the sorcerer spell list. You learn an additional sorcerer cantrip of your choice at 10th level.
Spell Slots: The Serpent table shows how many spell slots you have to cast your spells of 1st level and higher. To cast one of these sorcerer spells, you must expend a slot of the spell’s level or higher. You regain all expended spell slots when you finish a long rest.
For example, if you know the 1st-level spell false life and have a 1st-level and a 2nd-level spell slot available, you can cast false life using either slot.

Spells Known of 1st level and Higher: Starting at 3rd level, you know three 1st-level spells of your choice from the sorcerer spell list.
The Spells Known column of the Serpent table shows when you learn more sorcerer spells of your choice. Each of these spells must be of a level for which you have spell slots. For instance, when you reach 4th level in this class, you can learn one new spell of 1st or 2nd level.
Additionally, when you gain a level in this class, you can choose one of the sorcerer spells you know and replace it with another spell from the sorcerer spell list, which also must be of a level for which you have spell slots.
Spellcasting Ability: Charisma is your spellcasting ability for your sorcerer spells, since your power is drawn from your force of will. You use your Charisma whenever a spell refers to your spellcasting ability. In addition, you use your Charisma modifier when setting the saving throw DC for a sorcerer spell you cast and when making an attack roll with one.
Spell Save DC = 8 + your proficiency bonus +
your Charisma modifier
Spell attack modifier = your proficiency bonus +
your Charisma modifier
Innate Magic
Your magic is innate, truly coming from within. Starting at 3rd level, you may ignore any material components that do not have a listed price, as if you were casting with an arcane focus. You still must provide the spell’s verbal and somatic components.
While you do not require the use of a focus, you are able to use an arcane focus as long as it is on your body. Additionally, you may employ expensive material components as long as they are on your body. Most serpents embed these components into their scales.
If you multiclass as a sorcerer, this ability applies to your sorcerer spell slots as well. It does not apply to any other spell slots gained through any other means.
Channel Arcana
Starting at 7th level, you learn to channel your arcane power into destructive energy to enhance your attacks. When you hit a creature with your bite attack, you can expend one spell slot to deal damage to the target of your lineage energy type, in addition to your bite’s damage. The extra damage is 2d8 for a 1st-level spell slot, plus 1d8 for each spell level higher than 1st, to a maximum of 5d8.
You also gain a bonus to damage with your cantrips equal to your Charisma modifier.
Spell Resistance
Starting at 13th level, your close affinity with magic grants you advantage on saving throws against spells.
Scales like Steel
Upon reaching 18th level, you gain resistance to bludgeoning, piercing, and slashing damage from nonmagical weapons.
