Lineage Piece Haki Guide: Observation & Armament Questlines

Observation Haki (Level 500+)

The Observation Haki questline starts with Sogeking on Deeproot Jungle and costs 2.5M Yen at the end. It grants 10 dodges.

  1. Start the quest — speak to the Observation Haki NPC (Sogeking) on the jungle island.
  2. Defeat 40 World Bosses anywhere on the map.
  3. The torch puzzle — return to Sogeking, then find and light 5 torches hidden around the island. Lighting the fifth automatically awards the Observation Haki Book (untradeable quest item). Exact torch spots: torch locations guide.
  4. Unlock — hand the book back and pay 2.5M Yen.

A separate Obs Haki Book also exists as an ultra-rare drop (0.1% from any mob or boss) — worth knowing if you loot one before starting.

Armament / Buso Haki

Armament Haki is bought from the Buso Haki NPC rather than quested. Active effect: +25% player damage — it is the single cheapest damage multiplier in the game, take it as soon as it is affordable.

Haki Colors

Your haki rolls a random color when first unlocked. Colors are cosmetic; reroll them with a Haki Color Reroll item — 4% drop from any mob or boss, or guaranteed-pool loot from Rare+ chests. There is no separate haki leveling grind.

Which First?

Armament first for pure damage. Observation’s 10 dodges matter most for Extreme-difficulty bosses and dungeon runs (dungeon list), so pick it up before you start farming Yhwach-tier content.

Questions players ask

Real searches that land on this page, answered in one go.

What are the haki colors in Lineage Piece and which is best?

The official board does not list the colors or any stat tied to them — it only says Armament Haki "has a random color when first obtained" and that a Haki Color Reroll changes it. Color is cosmetic as far as the board is concerned; rerolls drop from any mob or boss at 4%, from Rare+ chests, or cost 7,500 coins at the Merchant.

How do I get Observation Haki?

Level 500+, then the Observation Haki NPC on Deeproot Jungle: defeat 40 bosses, light 5 torches (locations) to receive the Observation Haki Book, hand it in with 2.5M. It grants 10 dodges.

How do I get and use Buso (Armament) Haki?

Buso Haki NPC on Frostborn Island: 1 Haki Book + 1,000 gems. When activated it raises your damage by 25%.

How do I get a Haki Book?

Any mob or boss at 0.1% (~1,000 kills expected), or the Merchant in Lineage Town at 10,000 gems when it rotates in. The Book Exchange on Fossil Island also accepts 10 Haki Books for a Slime Orb.
