You've gazed into the Iris through years of meditation and became one with a new understanding of the universe and its balance. This provides you with new ways of channeling your KI.

Orbs of Destruction

Starting when you choose this tradition at 3rd level, orbs of energy hover around you. The number of orbs is equal to your wisdom modifier and you can't have more than that number of orbs hovering around you. As Bonus Action, you can regain any spended energy orbs.

You can hurl these destructive orbs of magical energy when you take the Attack Action (which dissappear when you hit or miss). When you do so, it counts as a ranged spell attack with a range of 30 feet. You are proficient with it, and you add your Wisdom modifier to its attack and damage rolls. Its damage type is force and its damage die is a d4. This die changes as you gain monk levels, as shown in the Martial Arts column of the Monk table. When you take the Attack action on your turn and use this special attack as part of it, you can spend 1 Ki point to make the special attack twice as a bonus action. When you gain the Extra Attack feature, this special attack can be used for any of the attacks you make as part of the Attack action.

 

Orbs of Balance

At sixth level, you meditate about destruction and see it as a tool, but a tool is not enough to find inner peace for yourself and others. You gain new ways of using your energy orbs.

Harmony: When you attack with the Orbs of Destruction feature, you can forgo one attack to spend one KI point and send an energy orb (which is spended) to an ally that you can see within 60 feet of you. This orb hovers around this ally and gives 1d4 plus your Wisdom Modifier of Temporary Hit Points to that ally at the start of its turn. This effect last for 1 minute or until that ally ends its turn more than 60 feet away from you or if it ends its turn out of your line of sight. You can have only one ally affected by this feature at a time.

At 11th level, the Temporary Hit Points given by Harmony increase to 2d4 plus your Wisdom Modifier, and 3d4 plus your Wisdom Modifier at 17th level.

Discord: As a bonus action, you can spend one KI point to send an energy orb (which is spended) at a creature that is hostile to you and your allies. Until the start of your next turn you and your allies can add one of your Martial Die to one roll of damage when you or them hit that target with an attack roll. Each creature can use this die only once per turn, including you.
This effect ends early if the target affected ends its turn more than 60 feet away from you or if it ends its turn out of your line of sight. You can have only one target affected by this feature at a time. 

These features do not end immediately when you regain your orbs using a bonus action (as stated in the feature Orbs of Destruction) and when either of Harmony or Discord end, the orbs used for them dissappear.

Orbs of Awakening

Starting at 11th level, when you finish a long rest you gain Temporary Hit Points equal to your monk level plus your Wisdom Modifier and when you finish a short rest, you gain only half your monk level (rounded down) plus your Wisdom Modifier in Temporary Hit Points.

In addition you gain proficiency in the Insight and Perception skills if you don't already have it. Your proficiency bonus is doubled for any ability check you make that uses either of those proficiencies.

Orbs of Volley

By 11th level, you've mastered control over your orbs and know how to unleash disquiet upon your adversaries. Your Orbs of Destruction attacks now have a normal range of 60 feet and a long range of 120 feet. You gain a new way to use your Orbs of Destruction:

You can use an Action to concentrate on all of the Orbs of Destruction that hover around you when you take this action and release all of them at once on a special attack using another Action at the start of your next turn. When you unleash these orbs you make an attack roll for each of them and you can choose the target (that can be the same target for all these attacks) for each one.

Until the start of your next turn, you can lose this concentration (as if you were concentrating on a spell) or choose to unleash half of the Orbs (rounded down) as a reaction following the same criteria above.

Orbs of Transcendence

At 17th level, you've achieved true inner peace and can embrace the Iris entirely.  You gain flying speed equal to your walking speed and can hover while you're not incapacitated or unconscious.

In addition, as an Action you can spend 5 KI points to adopt the form of the Iris, turning your skin and anything you're carrying into a golden color, gaining resistance to all damage and immunity to all conditions except grappled and restrained, also you shed bright light in an area of 30 feet around you. Each creature of your choice in that area (including you) regain Hit Points equal to five times your monk level when you adopt this form and at the start of your next turn.

This transformation last until the end of your next turn and while in this form you can't use the Attack Action, can't take reactions, cast spells nor use the Orbs of Balance's features, neither take the Orbs of Volley or Use an Object action.

Once you use this feature, you can't use it again until you finish a long rest.
