Jonah, the Darkin Scourge

"Jonah is a transform champion in the truest sense. Once a human adventurer, Jonah's exploits in an ancient ruin have left her cursed. She will soon succumb and become a monster the likes of which Runeterra hasn't seen for millenia.

Jonah experiences the last moments of her life on the Rift, and once she turns, there's no going back.

Starting the game with a strong supportive kit, Jonah's time as a human is spent assisting her allies, then planning for her dark future. By placing Momentos in strategic locations, Jonah will later gain boosts of power to make up for the lack of income as a support. Once the hunt begins, Jonah also slowly starts to siphon power from her foes, scaling into a true terror if her enemies allow her too much time."

Lore:

"Jonah was a middle-aged adventurer who spent much of her life filling out the ancient history of Valoran through her discoveries. After locating a previously unknown ruin deep in the earth, Jonah's career was cut short when she accidentally unleashed a powerful specter, becoming it's vessel. The specter - a Darkin spirit - incubated in her body before finally emerging and transforming its host. 'Jonah' is gone now... though memories still linger, driving the Darkin Scourge mad as it tries to recoup it's lost power."
