Way of the Feywild

This is designed to be a Feywild version of the Way of Shadow.

Fey Knowledge

When you choose this tradition at 3rd level, your special martial arts training with the Fey has led you to master a single melee weapon of your choice. You gain proficiency with that weapon, and it is considered a monk weapon for you. Your Fey masters also taught you how to speak, read and write Sylvan.

Additionally, your time with the Fey has gifted you the ability to duplicate the effects of certain spells. As an action, you can spend 1 ki point to cast Faerie Fire or Command, or 2 ki points to cast Hold Person or Silence, without providing material components.

Fey Step

At 6th level, you gain the ability to step between the planes, travelling short distances in the blink of an eye. As a bonus action, you can magically teleport up to 40 feet to an unoccupied space you can see. You then have advantage on the first melee attack you make before the end of the turn.
Additionally, your attacks with monk weapons count as magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage.

Cloak of the Wind

By 11th level, you have learned to become as fleeting as the wind. When you spend a ki point and use your bonus action on Step of the Wind, you may immediately turn invisible. You remain invisible until you make an attack or cast a spell.

Mage Slayer

At 17th level, you have learned to interfere with the flow of magic using your ki. When a creature within your reach casts a spell, you can use your reaction and spend 1 ki point to make a melee weapon attack against it. If you hit, the creature must succeed on a Constitution saving throw or the spell will fail, wasting any spell slots and material components in the process if applicable. If the creature failed the save and is also concentrating on another spell, it has disadvantage on it's save to maintain that concentration from the damage dealt by this ability.
