This balance mod alters the races of Oblivion to largely do away with natural immunities (and favoring resistances), while also restoring missing abilities seen in Morrowind (or those later added in Skyrim). In addition, a secondary goal is to have some racial powers and lesser powers continue to be useful into the late game.

UPDATE: Changes have been made to Redguard, restoring a 50% resistance to disease, removing the additional ability, and returning to what is far more similar to the vanilla Adrenaline Rush.

UPDATE: It seems that racial Fortify Attribute effects are dispelled at the end of the tutorial. The Imperial Luck ability has been replaced with a flat +10 racial bonus to Luck, instead.

UPDATE: After some testing, further tweaks have been made; the Highborn, Histskin, and Adrenaline Rush powers didn't have enough oompf to them, and so they were adjusted to have the 60-second duration as seen in Skyrim, and much higher magnitudes than the original "5 points for 30". In addition, it was discovered that the bonus to weapon damage from Strength caps at 100, greatly affecting the efficiency of Orc Berserk and Redguard Adrenaline Rush in the late game. They have both been adjusted and are now more distinct from one another.
