Swap one of your equipped Summoner Spells to a new, single use Summoner Spell. Each unique Summoner Spell you swap to permanently decreases your swap cooldown by 25s (initial swap cooldown is ? seconds).

Your first swap becomes available at 6 mins.

Summoner Spells can only be swapped while out of combat.
After using a swapped Summoner Spell you must swap 3 more times before the first can be selected again.
Smite damage increases after two Summoner Spell swaps.
