Demonic Infusion

You send demonic energy through a creature within range. If the target is willing, it will gain some demonic features, most often claws, fang, discoloured skin, glowing eyes etc. If the target is not willing, it must make a Charisma saving throw. Succeeding the throw causes no effects and the spell fails. Casting Demonic Infusion at different spell slot levels causes additional effects. Example: Casting Demonic Infusion as a 3rd level spell grants the target all the features up until the used spell slot I.E casting this spell as a 3rd level spell, you also gain the features from 1st and 2nd.  

• 1st level spell slot: A creature gains Fangs and Claws. When using unarmoured attacks, the damage is 1D4 Slashing (Claws) instead of 1 Bludgeoning and 1D6 Piercing (Fangs). Lastly, a creature gains Darkvision up to 60 feet.
• 2nd level spell slot: A creature gains resistance to Piercing, Slashing or Bludgeoning damage from non-magical weapons for the duration.
• 3rd level spell slot: A creature gains resistance to two other damage types (Magic included).
• 4th level spell slot: A creature gain Temp. hit points equal to the casters level + casting ability modifiers and the creatures total level.
