A shifter of werebear descent.

Encounter
Minor Action - Personal
Requirement: You must be bloodied.
Effect: Until the end of the encounter, you gain a +2 bonus to AC and Fortitude.
Ancient
A long-lost tribe of humans with connection to the primal spirits. Occasionally the hidden bloodlines will appear among humans even to this day.
As a subrace of humans, ancients can sellect any, all, or none of the following racial features
Ability Scores - Ancients gain +2 Wisdom, and +2 to either Intelligence or Constitution. This replaces the normal human ability score bonus.
Skill Bonuses - Ancients gain a +2 racial bonus to both Nature and Religion. This feature replaces the human bonus class skill.
Voices of the Lifestream - Ancients can learn the voices of the lifestream power. This replaces the heroic effort power or bonus at-will power.
Voices of the Lifestream
You hear the voices of the spirits, who guide you with advice.
Encounter
Free Action - Personal
Trigger: You make a skill check and do not like the result.
Effect: Reroll the skill checkl. Use the second roll, even if it’s lower.
Saarebas
Among some goliath tribes, those who can speak with spirits are called "the dangerous ones." Such mages are not sent to schools, but beaten and chained, to die as slaves to regain honor lost a birth. Are you such a slave, or have you escaped to determine your own purpose?
As a subrace of goliath, saarebas can sellect any, all, or none of the following racial features.
Ability Scores - Saarebas gain +2 Constitution, and +2 to either Charisma or Wisdom. This replaces the normal goliath ability score bonus.
Zealot's Volition - You gain a +1 bonus to saving throws against the restrained or immobilized conditions. This replaces the mountain tenacity feature.
Horned Giant - You gain a +2 bonus to Intimidate checks. When you make an Intimidate check, you may roll twice and use either result. This replaces both the goliath racial bonus to athletics and the powerful athlete feature.
