Description

The Mystery Summoner, formerly the Mystery Boss, is a boss enemy that summons Mysteries and rarely Mystery Bosses. With the Enemies Beta modifier active, it spawns Breaker2s and rarely Breaker4s. The Mystery Summoner does not spawn into anything when it is killed.

The Mystery Summoner, while having more health than the Speedy Boss, is slower than it. However, its main threat is the Mysteries and Mystery Bosses, or the Breaker2s and Breaker4s that it spawns. It also previously had Freeze Immunity.

Strategy

• A couple of high DPS towers such as Minigunners, Turrets, Accelerators or Rangers can kill this easily.
  • Additionally, you should use the Commander and DJ Booth to boost these towers.
• Try to kill the Mystery Summoner before it spawns a horde of Mysteries and Mystery Bosses, which may cause serious problems as they can spawn enemies with high health, such as the Slow Boss and the Speedy Boss.
  • For maps that have a distance between the entrance and where the main towers are, this enemy may pose a threat.
• Treat the Mystery Summoner like the Necromancer. Subdue the enemies it spawns, then focus on the boss.
  • For this reason, the Rocketeer, Mortar and Demoman can be quite useful against the Mystery Summoner as they can harm the enemies it spawns in large numbers.
  • Piercing towers like Archer or Shotgunner can also damage most or all of the enemies spawned if positioned correctly.
