Chemical Soul

Chemical Soul Sorcerers get their magic from chemicals, and acid, and usually have gained their power from the chemicals being injected into them somehow. They often enjoy using this power to hurt or heal their targets. 

Acidic Blood

Starting at 1st level, you become resistant to acid damage. You also gain proficiency with Alchemist's Supplies. 

Additional Spells

Also at 1st level, you learn the following spells which don't count against the number of sorcerer spells you know.

1st: Burning Hands, Purify Food and Drink
2nd: Heat Metal, Scorching Ray
3rd: Protection from Energy, Plant Growth
4th: Blight, Locate Creature 
5th: Antilife Shell, Cloudkill

Damaging Caster

Starting at 6th level, you become more attacking. When you cast a spell that does damage, you can spend a sorcery point to add an additional damage dice of the same time up to 3 sorcery points per spell. 

Alchemical Burst

Starting at 14th level, you can burst those who attack you. When you get hit with a melee attack, you can use your reaction to spend a sorcery point and cause the target to take 2d10 acidic damage. 

Soul of Fury

Starting at 18th level, you become immune to acid damage. Furthermore, when you deal a spell that does acid damage, you can spend a sorcery point and force the target to make a Constitution Saving Throw against your Spell Save DC. On a failed save, they become blinded for a minute. They can repeat the saving throw at the end of each of their turns.
