―Dispatcher on Wave 17 (Outpost 16)

Description

The Null Pyromancer, internally referred to as the Corrupted Pyromancer, was a support enemy that appeared in Outpost 16, Banlands and Blind Faith as part of the Null & Void Event. It had a decent amount of health and an above average speed. It also had the Freeze, Stun and Burn immunities, making it harder to apply effects to it.

The Null Pyromancer has one ability, where it will fire out corrupted flames from its mouth. This will set any tower hit on fire, applying a 30% Firerate Debuff that increased firerate by around 42.85% and a Scared Debuff which decreased tower range by 15%. Both effects lasted 6 seconds. If it hits a unit, it will deal 1,000 damage to them with its breath.

It can be spawned by the Null Commander, which boosts its Defense to 50%.

Logbook Description

"As the Null Pyro emerged from the Nil Zone's depths, purple sludge dripped from its gaping mouth. Pyro watched with a mixture of fascination and disgust, flames burning in his eyes as a creepy grin crossed his face. The creature rose to its feet, and as it stood, Pyro's flamethrower ignited."

Appearance

The Null Pyromancer is a corrupted version of the Pyromancer. It has purple skin. It wears a purple suit with black shoes, knee-pads, shoulder-pads, vest and a gas mask. It also has a few gas tanks on its back.

In its gas mask, it has a small gap where its mouth would be. This allows it to spit out corrupted flames which debuff towers.

Event Strategy

As this enemy only appears through Sandbox mode, no strategy section is made for its current version. Instead, a strategy section for the one that appeared without Sandbox mode in Outpost 16, Banlands and Blind Faith is listed instead.

• Towers with decent DPS, like the Golden Scout, Accelerator, Rocketeer, Ranger or Minigunner are recommended here.
• Because of its immunities, various debuffs do not work on it.
  • It cannot be knocked back by towers and stuns will only slow it down as it has the Stun Immunity.
  • It cannot be frozen, chilled or have its Defense reduced through chillness as it has the Freeze Immunity.
  • It cannot be damaged by burn or have its Defense reduced by it as it has the Burn Immunity.

Trivia

• The Null Pyromancer was unusual as it was one of the few enemies to actually buff towers rather than debuff them.
  • For whatever reason, its range reduction was actually a range increase, making it increase range of towers by 15%, though this got fixed in v1.78.0.
• The Null Pyromancer is unaffected by enemy appearance modifiers, such as Talk Like a Pirate Day.
