You were born with a horrifying ability but useful ability to swap bodies and take the abilities from that body.
Cursed Energy
Starting at 1st level, you can harness your negative feelings into a usable source of energy, called cursed energy. These feelings can be harnessed into attacks or abilities. The number of cursed energy you possess is based on your class, some classes use a modifier that being charisma or wisdom (Player’s choice)
Your cursed energy DC is 8 + user cursed energy ability modifier + proficiency bonus.
You regain all spent cursed energy on a long rest.
Graverobber
Starting at 1st level, you have a rather disgusting technique, which is frowned upon by the majority of sorcerers. When you have a humanoid creature’s corpse, you may spend 1 cursed energy during a long rest to put your brain on that creature through a transfer technique. This cursed energy spent cannot be recovered until your next long rest. While on the creature’s body, you lose any kind of racial features of your older body but keep all of your class features. You will gain the following benefits while inside the body:
- The creature’s racial features are now yours.
- The creature’s ability scores overwrite yours but you keep your Charisma, Wisdom, and Intelligence scores.
- The creature’s proficiencies and languages are now yours.
When you change into that creature’s body, it will look the same outside of having a scar on its forehead, which is a sign your brain is inside its body. You may pull the top of your head to show your brain, which is a normal brain with a human mouth. Other creatures may try to identify you’re not the humanoid by doing a DC 30 Insight check. Creatures who knew the body’s owner before you stole it may do the roll with advantage.
Skill Theft
Beginning at 3rd, your control over the body you take over increases. Starting at the third level you can choose to take one feature from the stolen body, you may choose two features at 6th, 11th, and 18th levels.
Immortality
At the 18th level, your age is the same as the body you take over, making you immortal as long as you keep switching bodies.
