A creature that develops this type of haki is able to use their powerful spirit to force others into submission. Users of this haki are able to easily dominate creatures with weaker willpower both physically and mentally through unleashing their auras. Creatures dominated by this power may either submit, flee, or become fully incapacitated by it. This haki can also be used like the Color of Armament to imbue attacks with energy, making them far stronger than normal. Only a handful of creatures on the planet can master this form of haki, allowing them to achieve heights very few have reached in power.
Color of the Supreme King Advancement
When deciding to advance your Color of the Supreme King Haki during a Spirit Surge Event, you may choose any of the following features below. The rarity of the haki advancement feature you may choose is determined by the Spirit Surge Event.
In order to gain a King's Haki Advancement feature, you are required to have "Qualities of a King" (see below), have a minimum Charisma score of 11, and meet any other prerequisites mentioned.
Alternatively, the DM may choose to permit certain player characters or NPCs to use Conqueror's Haki without needing to roll
Conqueror's Haki Spellcasting Ability
Wisdom is your spellcasting ability for your Color of the Supreme King spells, since the strength of this haki is determined by your willpower. You use your Charisma whenever a conqueror's haki spell refers to your spellcasting ability. In addition, you use your Charisma modifier when setting the saving throw DC for an conqueror's haki spell you cast.
Conqueror's Haki save DC = 8 + your proficiency bonus + your Charisma modifier
Conqueror's Haki attack modifier = your proficiency bonus + your Charisma modifier

Conqueror's Maelstrom
King's Haki Advancement, Legendary
Prerequisites: Dread Sovereign's Roar or Resonating Presence
Your will is a force of nature, an untamed storm that can bring even the skies to submission. Your potent Haki can resonate with the atmosphere itself, causing the elements to dance to the rhythm of your spirit.
As an action, you can choose to unleash the full might of your Haki, creating a spectacular atmospheric phenomenon known as a Conqueror's Maelstrom. A column of vibrant azure splits the sky directly above you, creating a heavenly chasm that can be seen for miles around. This imposing rift lasts for an hour, until you fall unconscious, or until you choose to dispel it (no action required).
This monumental shift in the atmosphere carries with it the following potent effects:
Authority of the Skies: Every creature within a 1-mile radius that can see the sky becomes instinctively aware of your imposing presence and your exact location. The sight of the split sky leaves an indelible impression of your might, potentially changing attitudes of creatures toward you at the DM's discretion.
Stormbinder's Will: You gain control over the weather in a 1-mile radius centered on you. As an action, you can change the weather conditions: from stormy to calm, from calm to a tempest, or create specific meteorological phenomena such as rain, snow, or dense fog. These conditions persist for the duration and revert to their previous state when the Conqueror's Maelstrom ends.
Shockwave of Supremacy: While Conqueror's Maelstrom is active, you can send forth a powerful shockwave of your haki as an action. Each creature of your choice that you can see within 300 feet of you must succeed on a Wisdom saving throw against your King's Haki save DC or be frightened until the end of your next turn. On a failure by 5 or more, a creature is also stunned until the end of your next turn, overwhelmed by the sheer might of your will.
