You see the icon of one ability. Guess which League of Legends champion it belongs to. For an extra challenge, show the icon in grayscale or rotated.
Once you find the champion, try the bonus round: was it their passive, Q, W, E or R?
Tips: look at the colors and shapes first. Fire, ice, shadows or nature often match a champion's theme, and projectiles, shields or dashes hint at their role. Grayscale removes the colors, so focus on the outline and the symbol inside the icon.
