Twenty-Firstborn - Big Ears

The Twenty-Firstborn do not have the largest ears of any races, potentially anyways but they certainly have the largest ears for overall body mass. They are rather small, shorter than the Fourthborn and are generally rather thin as well. Their ears however are very large and pointed. Their skin color ranges from a deep green to a fading green almost to a yellow. They tend to have claustrophilia as they seem rather elated to fit into the tiny never traveled areas of both nature and civilization. Pureblood

+1 Dexterity, +1 Wisdom
Ears to the Ground: A pureblood has a keen ability with their ears when placed against surfaces. They are rather sensitive to vibration and so long as they have their ear placed against a surface. Any solid surface that is within (Proficiency Modifier x Wisdom Modifier) times five feet can make perception checks adding their proficiency modifier on top of all other modifiers and can not be at disadvantage.
An Ear for Success: A pureblood has a particular connection to those around them, but not quite exactly themselves to the same proficiency. A pureblood has luck charges equal to their (Proficiency Modifier x Wisdom Modifier) and as a bonus action can effect any singular willing creature at the cost of one luck charge they can add their proficiency modifier to the next (Proficiency Modifier/2) rolls that creature makes. At the cost of effecting themselves it's two charges and using the ability on the same target will double the cost each until the end of the day. To regain any or all charges a long rest is required.

Halfblood

+1 Wisdom
Ludicrous Luck: A halfblood while perhaps is more perceptive than other Borns still have quite the knack for seeing the winds of fate and in essence luck. As long as they can influence the willing creature, be it touch, sound or otherwise as a bonus action the halfblood can increase the range in which the target can have a critical success by the halfblood's (Proficiency Modifer/2) for (Wisdom Modifier/2) rolls. They can use this ability (Proficiency Modifier + Wisdom Modifier) times before needing a short rest to get half the uses back or a long rest for all uses.
