When choosing your bloodline, you select a base race of human, duergar, or drow, as well as a subrace of bear, eagle, or wolf. Your ability score increases are given from your base race, while the subrace grants you your innate talents and features.

Bear - You grow long claws and gain an innate climbing speed equal to your movement. You gain advantage on Strength saving throws and become proficient in the Athletics and Survival skills.

Eagle - You sprout wings and gain an innate flying speed of 10 plus your movement. You gain advantage on Dexterity saving throws and become proficient in the Survival skill.

Wolf - You gain movement speed equal to 1.5 times your movement speed, rounded to the nearest 5. You grow large teeth and can choose to strike with them as an unarmed strike. This attack does 1d6 + STR piercing damage. You become proficient in the Acrobatics and Survival skills. 

Because of the mixed bloodlines that these experiments produce, you gain a primal spirit based on your sub race. These spirits are tied deeply with your animal bloodline, and you can access some of the most primal instincts of these animals in times of great need. You can only unleash your primal instinct once per long rest. 

Bear – Having the primal spirit of a bear inside you, you can unleash your instinct in a Primal Roar. This roar causes any hostile creature, or those unaware of your true nature to make a Wisdom saving throw or be frightened of you for 1 minute. Your facial appearance during the roar becomes that of a full bear’s.

Eagle – Having the primal spirit of an eagle inside you, you can unleash your instinct to track a creature. You get advantage on all survival checks made to track that creature, and if time comes to attack said creature, you get advantage on all attacks made to that creature. These advantages end after 30 seconds of the creature being found, or after eight hours if the creature is not found.

Wolf – Having the primal spirit of a wolf inside you, you can unleash your instinct to Gruesomely Attack one creature. When taking the attack action on a creature, you can perform a whole turn of action twice, however, both actions must be used to attack the creature. The first attack to hit after using this feature automatically critical, however the rest of the attacks then become unable to score a critical. 

When choosing your bloodline, you select a base race of human, duergar, or drow, as well as a subrace of bear, eagle, or wolf. Your ability score increases are given from your base race, while the subrace grants you your innate talents and features. 

Human - Your ability scores each increase by 1, or you can select 2 ability scores to go up by 2.

Duergar – Constitution goes up by 2, and Strength goes up by 1. You also gain Superior Darkvision, and at 5th level you gain the ability to cast Invisibility once per long rest.

Drow – Dexterity goes up by 2, and Charisma goes up by 1. You also gain Superior Darkvision and learn the Dancing Lights cantrip. At 5th level you learn the Darkness Spell, and can cast it once per long rest.

Experiments tend toward neutrality, being more focused on survival than concepts of good and evil. 

You can speak, read, and write Common and Undercommon.
