Available after completing the quest Save My Son, these experts in monster research have trained tirelessly to communicate with, and even control the animals of Vana'diel. Based on their knowledge of beasts, Beastmasters (BST) can charm the beasts of Vana'diel to fight alongside them, call beasts to their side, and intimidate enemy beasts of Vana'diel.
Beastmasters are generally considered the best solo class in the game. Beastmasters often can be found soloing monsters or teaming up with other Beastmasters in all Beastmaster parties. Beastmasters are less frequently found in conventional parties. In a conventional party, a Beastmaster will most frequently fill the roles of damage dealer and puller, and augment their damage with properly selected "Jug Pets". When soloing, it is very important that a Beastmaster select the proper camp.
No experience point penalty is incurred while using charmed pets or pets summoned by Call Beast.
If the Beastmaster uses a pet of a higher level than the highest level party member, the pet's level is used as the highest level party member for purposes of calculating Experience Points. A Beastmaster's pet has no other effects on Experience Points.
