Demonic Soul

In a ritual you traded a piece of your soul to a demon for your understanding of sorcery. In exchange for a part of your soul you received a piece of demonic soul, imbuning you with demonic magic. As a result, you can not set or change your alignment to 'good'.

In addition, the DM may roll a 1d20 everytime you interact socially. When the dice shows a 6 or 13 the DM or (at the DM's discretion) the player may speak as the demon.

Demonic Spellcasting

Starting at 1st level, your demonic soul fragment grants you the ability to learn spells from the demonic spell list below:

• 1st level: Demonic Icicle
• 2nd level: Charred Soil
• 5th level: Rending Frenzy
• 7th level: Demon Form
• 8th level: Demonic Vessel

In addition, you can speak and write Infernal.

Demon Possession

Starting at 1st level, you can use an action in your turn to prepare a possession. You can select one creature that you can see, which is only up to 1 size category bigger than you, to possess. Once the creature starts it's turn it may make an Insight (Wisdom) Saving throw (DC 10 + your sorcerer level). If the creature fails the save you have full control over the creature untill the end of its turn and can use it's actions freely. If the creature succeeds the saving throw, it can fight back against your possession, but is immobilized untill the end of its turn.

Blindsight, Blindsense and Darkvision enhance this ability.

You can use this feature only once per long rest. At level 6 and 13 you learn to possess an additional time for every long rest and at level 15 you may use this feature thrice for every short or long rest.

In addition, the DM may roll a 1d20 everytime you interact socially. When the dice shows a 6 or 13 the player is possessed by the demon and the DM or (at the DM's discretion) the player has to speak as the mallicious demon.

Demons are usually chaotic evil and want to bring despair and mischief, but they are not stupid. A demon will not bring itself and it's host in immidiate danger, but they love to hurt people, physically and psychically.

Devil's Eyes

At 6th level, your demonic part turns your eyes permanently black and you receive Blindsight (90 feet).

Impish Wings

At 14th level, you gain the ability to sprout spectral, demonic wings on your back, gaining a flying speed equal to your current speed and you are able to hover in the air. You can create these wings as a bonus action on your turn. They last until you dismiss them as a bonus action, get incapacitated or die.

Demonic Symbiosis

Beginning at 18th level, your demonic presence and you have engaged into symbiosis. The demon deflects projectiles, rendering you immune to them.

As a part of the symbiosis, your character is forced to align as 'evil' from now on. The demon may no longer interfere into conversations, the player made it part of himself.
