Summoner is a game boss that can be found in The Gauntlet at each 10 levels, or in Trials as a random end boss.
Summoner is a boss that can summon creatures to help him in fight. His outer look is just the same as any other summoner in the game, however he is 3 times bigger than the normal summoner. He can usually say the words like other summoners, for example "Ragadam is here!".
This boss can shoot fire arrows on you that cause several damage to your hero.
