The Yuan-Ti were a race of humans who turned into snake people, due to their fascination of snakes and their figure. Those who choose this subclass must expect fear and shock as they walk pass, which is often something that these sorcerers embrace. As the sorcerers walk this fine line, consider their motives and the reasoning for why they do this - do they do it because they wish to resurrect the Yuan-Ti empire themselves, or are they doing it simply for power? Think about this when creating a character with this subclass.

Colonial Presence

At 1st level, when you cast a spell, you can cause your body to alter whilst casting it. You can spend 1 sorcery point in order to alter something about you that could give you the upper hand in battle. When you choose this option, roll a d20 and the number on the die corresponds to the table at the bottom of the page. The effect of the Colonial Presence feature lasts for 3 rounds, increasing to 4 rounds at 9th level and 5 rounds at 18th level. The higher the spell level, the more dice you roll and you can choose which dice you want. 

The details of the Colonial Presence table are shown below.

Colonial Presence Ability Table

Here is a list of all the abilities that are granted when you use the Colonial Presence feature.

Fail To Call

Your call to the Yuan-Ti which resides in your blood fails, leading to the inability to use this feature until you take a short or long rest. This happens when you roll a one or a nineteen on the d20.

Snake Tail

When you use your ability, you gain a large snake tail, losing your feet and legs, allowing you to constrict enemies, with the same DC and damage as the Yuan-Ti Abomination. You also gain resistance to poison and acid damage. However, if this effect is rolled twice in a row, your veins burst with poisonous energy, dealing 2d6 force damage to yourself and everyone in a 10ft radius must make a DC 18 dexterity saving throw or take 6d6 poison damage, taking half as much on a successful save.This happens when you roll a two, a three or a four on the d20.

Reptile Arms

Your call to the Yuan-Ti gives you snakes for arms, so when you make an attack, the snakes make seperate attacks as you do so. They can also make opportunity attacks seperately to yourself. These snakes have the same stats as snakes from the Monster Manual. You also gain resistance to poison and acid damage. However, if this effect is rolled twice in a row, your veins burst with poisonous energy, dealing 2d6 force damage to yourself and everyone in a 10ft radius must make a DC 18 dexterity saving throw or take 6d6 poison damage, taking half as much on a successful save.This happens when you roll a five, a six or a seven on the d20.

Serpentine Head

When you use this ability, you gain the head of a Yuan-Ti, giving you an increase of +2 charisma and +2 wisdom, no matter the ability score you have already. You also can spend an extra sorcery point to make everyone in a 20ft radius make a DC 16 wisdom saving throw or be frightened of you until the Colonial Presence feature ends. You also gain resistance to poison and acid damage. However, if this effect is rolled twice in a row, your veins burst with poisonous energy, dealing 2d6 force damage to yourself and everyone in a 10ft radius must make a DC 18 dexterity saving throw or take 6d6 poison damage, taking half as much on a successful save.This happens when you roll an eight, a nine or a ten on the d20.

Green Scales

You gain the scales of a Yuan-Ti across your arms and chest, giving you a +2 to strength and a +2 to AC, which goes on top of the broodskin ability. At 7th level, these modifiers increase by 1 and increase by 2 at 14th level. Additionally, you gain immunity to poison and acid damage. This happens when you roll a thirteen or a fourteen on the d20.

Yuan-Ti Magic

Your magic begins to take a poisonous twist, as you learn two different spells which deal poison and acid damage with no additional spell cost for 5 hours, when they fall from your memory until this ability occurs again. At 7th level, this increases to three and then to four at 14th level. However, if this effect is rolled twice in a row, your veins burst with poisonous energy, dealing 3d6 force damage to yourself and everyone in a 10ft radius must make a DC 18 dexterity saving throw or take 8d6 poison damage, taking half as much on a successful save.

When this ability comes into effect, your alignment changes to Neutral Evil and you need to make a DC 14 wisdom saving throw to maintain control of your mental stability. If you succeed, you are fine, but if you fail, you attack the nearest person to you that isn't a Yuan-Ti. This happens when you roll a eighteen on the d20. 

Full Yuan-Ti Transformation

Your call succeeds almost too much - you become a full Yuan-Ti Abomination, gaining the same HP and AC as them, as well as increasing your strength, wisdom and charisma by 2, no matter your current ability scores.
