Fey Blood Magicks

Due to the fey blood running through your body, spells you cast from the enchantment or illusion schools have additional effects:

• Creatures have disadvantage on discerning your illusions and resisting your enchantments
  • You can give yourself advantage instead if these require you to roll.
• You can double either the size or duration of illusions
• You can double the duration of enchantment effect.
• If they require concentration they no longer do.
• You can remove the somatic and verbal components

You can only have a spell affected by one of these effects at a time.

Essentially you get the metamagic options from sorcerer but extra.
