Oath Tenets:

Pledge of Guardianship: I swear to protect the innocent, uphold justice, and stand as a guardian of all life. With this ring, I pledge my will and my heart to the cause.

Light in Darkness: In the darkest of times, I will be a beacon of hope and courage. My light shall pierce through despair and bring illumination to those in need.

Unyielding Will: I will stand firm in the face of adversity, my will unbroken and unwavering. I shall overcome challenges, and my resolve shall never falter.

Unity of Purpose: I recognize that true strength lies in unity. I shall work alongside my fellow guardians, supporting and aiding them in times of need.

Limitless Imagination: With the power of will and imagination, I shall create constructs of virtue and might. I shall use this power to shape a better world, bringing forth the force of creation.

Ring of The Emerald Guardian

When you choose this subclass, a brilliant emerald ring that you are immediately attuned to appears and situates itself on your finger, granting you the ability to create constructs.

Properties:

• While attuned to the ring, you can use your Charisma modifier instead of your Strength or Dexterity modifier for attack and damage rolls with melee weapon attacks. Additionally, your unarmed strikes deal 1d8 force damage.
• The ring has 3 charges, and it regains 1d3 expended charges at dawn. You can expend a charge to create a simple construct that obeys your mental commands. The construct's statistics are determined by the DM based on its form and abilities.
• As a bonus action, you can create a forcefield around yourself or an ally within 30 feet, granting them temporary hit points equal to your Charisma modifier + your character level.
• The ring can create light equivalent to a torch as an action, or you can expend 1 charge to create the effect of the Daylight spell.
• You can use the ring to communicate with other creatures attuned to a Green Lantern ring within 120 feet as long as they are on the same plane of existence.

Abilities:

• Construct Mastery: You gain proficiency with martial weapons and shields while attuned to the ring.
• Energy Projection: As an action, you can expend 2 charges to unleash a beam of pure energy. Make a ranged spell attack against a creature within 120 feet. On a hit, the target takes 4d10 force damage. The damage increases by 1d10 for each additional charge expended.
• Emerald Aura: As an action, you can expend 1 charge to create an aura of green light around you. Creatures of your choice within 10 feet of you have resistance to radiant and necrotic damage. The aura lasts for 1 minute.

Channel Divinity

When you take this oath at 3rd level, you gain the following two Channel Divinity options.

Emerald Resurgence

Starting at 3rd level, you can use your Channel Divinity to tap into the ring's power and restore your own vitality or that of an ally. As an action, you can touch a willing creature or yourself and expend a use of your Channel Divinity. The target regains hit points equal to 2d6 + your Charisma modifier. (Becomes 3d6 at 6th level, 4d6 at 10th level, 5d6 at 14th and 6d6 at 18th level)Additionally, the target gains temporary hit points equal to your Charisma modifier.

Emerald Fury

Starting at 3rd level, you can use your Channel Divinity to tap into the raw energy of your oath, unleashing a burst of emerald fury upon your enemies. As an action, you can unleash a wave of energy in a 30-foot cone originating from you. Each creature in the cone must make a Dexterity saving throw against your paladin spell save DC. On a failed save, a creature takes radiant damage equal to 2d8 + your Charisma modifier and is blinded until the end of its next turn. On a successful save, the creature takes half damage and isn't blinded.

Additionally, creatures that fail the saving throw have disadvantage on attack rolls against you until the start of your next turn, as the emerald energy continues to emanate from you, disrupting their focus.

Once you use this Channel Divinity option, you can't use it again until you finish a short or long rest.

Oath Spells

You gain oath spells at the paladin levels listed.
