Sah'Kla, the Sin of Beauty is a SMNK custom champion series.
A marksman with potent spells, Sah'Kla is extremely fragile in compensation, with health, armor AND magic resist all close to being the worst in the game. She's triply more fragile as she uses health as cost to her abilities, decreasing her already little sustainability.
Her resource is listed as Blood Well, but it's the similarly functioning Ichor. The ichor gauge's cap starts at 30, and increases by 45 per level.
A being from the Void, Sah'Kla is moved by only one thing: learning all charms her surroundings has to offer, and lure anyone into giving themselves to her. She doesn't just ensnare her victims of choice or bow them down to her will, she absorbs them, or worse. Charm spells, fake benevolence, anything is a valid excuse for her to gain more twisted ways to rob victims of their being. Nobody has ever known her true motives in gaining power up to recently, and becoming the most beautiful being in existence is but her means to the end of all Voidborn: open a gate between the Void so that the Void will eventually consume all of Runeterra.
