Cornelia, the gunner of Alvoan
Concept of this champion was hybrid marksman, that would work similar to clasical AD carries, while being able to use 1-2 AP or hybrid items. To achieve proper hybrid, I decided to give certain stats aditional efectivity - Make AP increase crit damage and chance(Passive) and make AD increase armor and mr shred on her Phantom bullets. Before calling this OP, compare with yasuo's dual crit effectivity.

To achieve balance while maintaining strong scalings and abilities, Cornelia's ultimate is weaker(becoming probably weakest ultimate in game) and her basic AD and AD per level is really low. Moreover, her only escape is movement speed bonus on her Q, which is insignificant on lower levels.

As her ad is lower than ad of other marksman, so is lifesteal effeciency. To make up for that, she gets aditional shield type tankyness, with passive on Phantom Bullets, that is similar to lifesteal - every autoattack grants low ammount of shield. This shield scales with AP, further improving AP effeciency.

As this concept stands, Cornelia can be build either hybrid, full ad or even full ap, where each build has different type of power.
