League of Legends Summoner Spell: Challenging Smite

Deals 390-1000 true damage (depending on champion level) to target monster or enemy minion. When cast on enemy champions, reveals the target, reducing their damage by 20% and marking them for 4 seconds. While marked, your basic attacks apply a burning effect to the target that deals 60-162 (based on level) true damage over 3 seconds. Does not trigger spell effects. 15 second cooldown.

Smite regains a charge every 90 seconds, up to a maximum of 2 charges.

Smiting large monsters grants a heal for 70 (+10% max health).

Challenging Smite is unlocked by purchasing Skirmisher's Sabre.
