Observation Haki

Observation Haki is a special ability that allows its users to focus in and heighten their senses to the point of superhuman levels. This ability can be unlocked through many different ways, such as training or a stressful moment in battle. The stressful moment is up to the DM.

There are three types of Observation’s Haki (Intent, Strength, and Presence), and each one of them can level up to 5. When you first unlock Conqueror’s Haki, you can choose which type you want to put your first level in, while the rest remain at level 0. 

Every 250 Willpower, you can increase 1 Observation Haki type by 1 level. Though if this overlaps with any other opportunities to level up different Haki types, you must choose only 1. Please keep track of your levels in your note section on D&D Beyond.

Once activated, the user can see the aura of others within a certain radius. This radius is equal to the user’s willpower in feet. For example, if the user has 182 willpower, they can see auras up to 182 feet away. Without specialisation though, these auras can’t tell you anything.

Observation Haki - Intent: When you activate Observation Haki, you can see a creature’s intent based off of their aura as long as they're in your Observation Haki’s range. This intent ranges from a creature’s alignment or their feelings. When looking at aura’s through the veil of intent the colour dictate their alignment and shape their feeling

Blue - Neutral

Green - Good

Red - Evil

Jagged - Chaotic

Smooth - Lawful

Wavy - Neutral

These emotions tell you info you can take advantage of.

Depending on your level of intent, you can sense others of your level and below. For example, someone with level 3 Intent can sense the intent of someone with level 2, but not someone of level 5. In a circumstance where they have the same level, it only matters who has the higher willpower.

Observation Haki - Strength: When you activate observation haki, you can sense a creature’s strength based on how large their aura is. Depending on how much stronger or weaker a creature is than the user, their aura will be bigger or smaller. However, a creature with a high enough level of strength sensing can mask their strength so that their aura is constantly changing. This doesn’t mean they are stronger than them, it only means their level of strength sensing is higher.

Depending on your level of strength sensing, you can sense others of your level and below. For example, someone with level 3 strength sensing can sense the strength of someone with level 2, but not someone of level 5. In a circumstance where they have the same level, it only matters who has the higher willpower.

Observation Haki - Presence: When you activate Observation Haki, you can see a creature’s aura even behind walls or other obstacles of your level and below.

Depending on your presence sensing level, you may be able to hide yourself if you’d like from others using this ability, or vice versa. For example, someone with level 3 presence sensing can see people with level 2 presence sensing or hide themselves from that level, but not someone with level 5.

Starting at level 1 of Presence Sensing, if an attacker is trying to surprise attack you, and your willpower is higher than theirs, then you can roll a dexterity saving throw to attempt to dodge the attack.

Additionally, you may activate Observation Haki to give yourself Advantage and add your Presence Sensing level to your next ranged weapon hit.
