Some abilities, such as Renekton's slice and dice, have obvious ability icons, while others, such as the Royal Privilege have nothing that directly connects them to the champion.
In today's challenge , the ability of the day is: "Royal Privilege". At first glance, it doesn't look like much of anything, if you don't know the lore of the League of Legends champion it's connected to.
The answer to which LoL champion uses Royal Privilege is Qiyana. She is an Ixtal princess, who has been trained in the arts of her homeland and can manipulate all magical elements.
It is, in fact, her passive ability, and the basis for her entire trading pattern. Its effect is that Qiyana's first basic attack or ability against each enemy deals bonus damage.
Interestingly enough, this ability had a bug tied to it not too long ago, when used in conjunction with the First Strike rune. Due to the bonus damage dealt by the ability, the First Strike rune would proc twice when Qiyana used it.
As you can guess, this meant that Qiyana had more early-game damage for trading due to this, as well as double the income from the First Strike rune, making her basically unstoppable in lane.
