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 @f3@ 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.
