Description

The Mega Frost Mystery is a summoner enemy that appears in the Frost mode. It has a decent amount of health and above average speed. When killed, it will summon five random enemies.

Logbook Description

"The Frost Mystery is considered one of the most terrifying creatures in the Frost Realm. It has an exoskeleton made of tough solid ice, while its insides contain water that cannot be frozen. According to legend, these beings are created from those who fall through frozen lakes and never resurface. The shadowy figure visible within is believed to be one of these unfortunate souls. It releases frost enemies with modifiers upon death."

Appearance

The Mega Frost Mystery is an entity with an exoskeleton made entirely out of tough, solid ice filled with unfreezable water. Inside its torso, it contains a shadowy figure in it, which has an entirely white body.

Enemies Spawned

The Mega Frost Mystery summons five random enemies from a set list, all with their own chances of being chosen. It can summon the following enemies:

• Yeti (27.27% chance, 0.5 delay)
• Packed Ice (27.27% chance, 0.7 delay)
• Blizzard Wizard (18.18% chance, 0.8 delay)
• Frostbane (18.18% chance, 0.8 delay)

Strategy

• Towers with good DPS, like the Accelerator, Turret, Ranger and Pursuit are recommended against this.
  • AOE towers like the Rocketeer or Mortar can also be useful at clearing out multiple of them at once.
