Lunar Sorceress

The Lunar Sorceress appears to be a powered up version of CC's Valentina.
 * Her skill Moon Grace has about the same effect of Love Cyclone at the next level up.
 * Her much higher level of Crit Resist shielding for allies matters more in CoD, given Armor granted Crit values.
 * Her ATK SPD is 1000ms instead of 1200ms.
 * She has 36% more hit points and her move speed is 35 units faster.

Combo with Ra
Normally Ra can only proc every 1.4 seconds or so because it's hard to add energy to him. At skill level 10 LS is adding 40 Energy per second to Ra, for four out of six seconds. For each of these boost seconds Ra only needs to attack (or be attacked) four times to reach 100 energy. That's a cycle time of 0.8 seconds letting Ra stack up several times more.

This is in addition to recovering from Maahes' King's Fury of course.
