Summoner spell

Spells are the summoner bound abilities.

Summoners are allowed the use of two summoner spells during any fight in the Fields of Justice. They are selected during the Champion Selection before each match and cannot be changed for the duration of the match. These spells have a direct impact on the action in the battle arena.
