League of Legends Lillia can be a solid pick on both the top lane and in the jungle, with her speed, damage, and the CC offered by her ultimate offering the perfect tools for demolishing opponents in the popular MOBA. A player has discovered that the Bashful Bloom also has a pretty overpowered combination of ults in Ultimate Spellbook, enabling her to put the entire enemy team to sleep instantly.

For the uninitiated, Ultimate Spellbook is a limited-time game mode on the Rift. It goes the same way a regular match does, except everyone has the option to choose another ultimate ability to go along with their own. So, you could be a Nasus with Cho’Gath ult, for example (a disgusting combination), and be an absolute giant by the end of the game.

Lillia’s ult, Lilting Lullaby, enables her to put an enemy to sleep providing they’ve recently been affected by her passive ability. A player has discovered that pairing this ult with a Karthus one enables Lillia to damage every member of the opposing team, then immediately put them to sleep.

Being able to CC an entire team is incredibly strong; not only does it enable your team to dive their opponents, regardless of position, but each time an opponent wakes up from the Lillia ult, they take a sizable chunk of damage.

Karthillia isn’t the only overpowered combination on Ultimate Spellbook, with some additions capable of tipping a champion over the edge.
