Reilath and Thalier, the Spectral Twins are a combined custom champion in League of Legends. Their kit is . . . unique to say the least. Two regular abilities (each side), an ultimate, and an no-rank "r." This means that the A"q" and "w" abilities will both have seven ranks, instead of five, and the "e" will have four. One side is AD focused, while the other is AP. Building both will be a challenge, as well as a boon/burden relationship. Different abilities will do less damage than with an AD or AP focused build, yet all will be usable for damage in the end.
Theoretical Item Build
VERY unfinished. When time permits I will complete this champion.
