Beastmaster

Beastmaster was the name of the human who were able to trigger spiritual resonance with the Beast Cards.

To become a Beastmaster one has to surpass a beastmaster aptitude test before the age of eighteen.

When a mysterious resonance between the beast card and his soul is born and a mystical space called Spiritual Sea appears in the mind one becomes officially a Tier One Beastmaster.

If a beastmaster wished to make use of a beast card, they had to first trigger spiritual resonance with the card and store it in their spiritual sea, before branding them with their Spiritual Imprint.

Similarly, if a beastmaster wished to gift or sell their beast card to others, they had to first remove their spiritual imprint. Otherwise, even if the opposing party had the card in hand, they wouldn't be able to use it at all.

To grow stronger a Beastmaster cultivates Soul Force. The easiest way to cultivate is to kill Exotic Beasts.

Soul Force
Killing Exotic Beasts raise the Soul Force, but the quantity changes on the Rank of the Beast killed.
 * Black Iron: 1 Points of Soul Force x Star Rank
 * Bronze: 2 Points of Soul Force x Star Rank
 * Silver: 4 Points of Soul Force x Star Rank
 * Gold: 10 Points of Soul Force x Star Rank
