Dwarfs have affinity with earth.

The Slazs born with ice or water.

Salamanders have a lot of fire affinity.

If there affinities are increased for a long time, without changing the type of element, sometimes one ends up by waking up a symbiosis.

These are usually extreme ways of manipulating the element in the shape of an attack or depense though sometimes they can be trained in other ways, like that salamander did.

No one knows exactly how or why they appear and work, when experienced hunters reach some point they hear strange words and begin to show symbols, which unleash the symbiosis.

The only sure thing is that they are very powerful skills that cannot be chosen every person wakes up a personal power that can take many years to show up, or never.

Nevertheless, a symbiosis is not necessary to take use the affinity, a hunter can train in manipulating his element to learn special techniques of less power.

The call of thunder is a very versatile salamander skill, witch can be used in different ways according to the affinity level obtained.

The most skilful hunters can have affinities so strong that they show up some symbols due to the injected power some of them are so powerful that they lock like low level symbiosis.
