[edit] To become a Beast Master

A lvl 30 Archer can become Beast Master by first going to Emilia in Rockslinwood. Then you must get the 4-part quest "Way of the Beast Master." For the fist part, you need to collect 30 Weeds from Herb Gathering. Next you must get 30 Porks from Pig Dumplings. Then you must get a Firebird Seed, an Aqua Seed, a Wind Seed, an Earth Seed and a Diamond Flower Seed. Firebird seeds are found from imperial herbs and the other seeds are from common herbs. Lastly you need to buy a 2nd Advanced Class License from any weapon seller, you need 1000 Gold and 1000 Victy to purchase it.

[edit] Beasts

A Beast Master's skills focus around calling beasts to assist you in battle. Beasts stand by their master's side until the Beast Master orders them to attack. Each beast has a different attack. The first Beast Master skill is Roaring Wolf. This beast has 10 health at lvl 1 and bites on an enemy causing damage over time. Beasts dissapear once their summon time runs out. Beasts also have HP that can be used to protect their master, once they run out of health they dissapear.

[edit] Archer - Beast Master

Beast masters are archers who are close to nature and thus have strong rapport with animals.

Beast masters are the masters and the friends of beasts.

Wherever they are beast always reply to their call and gladly fight for them.

Beast masters care for nature and their beast friends.

We can find a record from King 's Ancient Library that all the animals in Beuritania cried sorrowfully when the great beast master Jucibird died.
