So, reading this quote, we can surmise that it was said by someone who is either a schemer of Runeterra or has the ability to literally tangle webs. Why not both?
In today's challenge, the quote of the day is: "Ah, the tangled webs we weave." It immediately makes us think of champions that have a background of scheming, as well as the corresponding arrogance . Oh, and also web design.
The answer to the question of which champion in League of Legends says: "Ah, the tangled webs we weave.", is Elise.
Elise is a deadly predator who dwells in a shuttered, lightless palace, deep within the oldest city of Noxus. Once mortal, she was the mistress of a powerful house, but the bite of a vile demigod transformed her into something beautiful, yet utterly inhuman, a spider-like creature, drawing unsuspecting prey into her web.
To maintain her eternal youth, Elise now prefers to feed upon the naive and the faithless, and there are few who can resist her seductions. Her main purpose in life is to lead offerings to her master, Vilemaw, which resides on the Shadow Isles.
Vilemaw is currently a being comparable to the Freljordian demigods, or perhaps even Nagakabourous, and is theorized to have come from beyond the stars.
