Kokoto Village Unlockables

After Clearing the Rathalos Urgent Quest that unlocks 5-Star, speak to the Village Elder who will direct you to go behind your house and retrieve the Hero's Blade sword.

After Clearing the Monoblos Urgent Quest at the end of the main quest line, speak to the Village Elder for a Hunter's Citation, required to upgrade the Hero's Blade. You will also need the extremely rare Monoblos Heart.

The Legendary Blades require an additional item: the Kokoto Village Chief's Old Sword.

Slay 20 or more of each Wyvern and speak to the Village Chief to receive the Early Bird Piercing.

Online Tickets
Crowns and Subspecies Quests

Quests to hunt a monster subspecies must be unlocked by successfully hunting a specimen of the common species of a large enough size. If a monster is unusually large, you will be awarded an appropriate Crown mark on quest completion, which is visible in your monster reference once you buy the associated book for that monster.

(See the Bestiary page and individual monsters for more details on exact sizes per crown.)

The White Monoblos quest, and the Village and High Rank Pink Rathian and Azure Rathalos quests only require a silver crown. All other subspecies can only be hunted in G Rank, and require a gold crown to unlock their quests (this includes any G Rank Pink Rathian and Azure Rathalos quests.)

There are a few notable exceptions to these rules:

Note that silver and gold crowns are not distinguished between common and subspecies monsters; that is to say, a subspecies crown will count for the species and vice-versa.
