Preview page based on Riot dev updates for Patch 26.12. Names and broad mechanics are official, but exact tuning and live stats may change before or after release.
Quick read
Riot says Quest: Tooth Fairy makes enemies drop a tooth after a burst-damage window. Each extracted tooth grants Lethality and Magic Pen. Burst champions are the first theorycraft bucket until live data lands.
What Quest: Tooth Fairy does
Riot describes Quest: Tooth Fairy as a quest where dealing a chunk of damage within a short window causes an enemy champion to drop a tooth. Each tooth grants Lethality and Magic Pen.
Likely champion fits
Early candidates are champions who can reliably compress damage into short windows. Assassins, burst mages, and poke champions with repeatable combo patterns are the first places to test.
What to update later
After launch, add exact damage thresholds, stat values per tooth, stack behavior, and champion win-rate signals once enough games are available.
