Santa-NK1 is a Hardmode, mini-boss that spawns during the Frost Moon event. When below half health, the face and beard of the Santa mask will be torn apart to reveal a rather morbid skull underneath.

Attack Phases[edit | edit source]

Santa-NK1 repeatedly cycles through three attack phases:

  • First phase: Chain gun fires bullets at the player.
  • Second phase: Presents launch high, then rain down via parachute from above, causing damage on contact with players. These travel through blocks.
  • Third phase: Rocket barrage. These also travel through blocks.

While moving, it also drops large spiked balls on the ground that deal high damage (120-150+ with Chlorophyte armor). These increase in frequency as Santa-NK1 takes damage.

Notes[edit | edit source]

  • Santa-NK1 currently has one of the highest damage rates in the game.
  • He also has one of the highest defenses in Terraria, at 56.
  • The drop chances of the items increase somewhat linearly from wave 7 to 20. See the collapsed section below for more information.
  • The chance the Santa-NK1 will drop items is determined by the formula 1 / floor((30 - wave) / 2.5), which at the minimum and maximum waves the Santa-NK1 appears, evaluates to 1/9 - 1/4 (11.11% - 25%) as the wave increases. If the Santa-NK1 does end up dropping an item, there will be a 50% chance that either the Chain Gun or Elf Melter will drop, which makes the drop chance for each item effectively 1/18 - 1/8 (5.55% - 12.5%).
  • In Expert mode, the formula for dropping an item becomes 1 / (floor((30 - wave + 7) / 2.5) - 2) which changes the chances to 1/4 - 1/1 (25% - 100%), making the chances for each individual item 1/8 - 1/2 (12.5% - 50%).
  • Santa-NK1's trophy will only drop if the 11.11% - 25% / 25% - 100% Desktop VersionConsole Version succeeds and a few more checks pass. If the wave is greater than 15 (8 in expert mode), then the drop chance adds on another chance based on the table below:
Wave Chance
15-16 / 8-9 Desktop VersionConsole Version 1/4
17-18 / 10-11 Desktop VersionConsole Version 1/3
19-20 / 12+ Desktop VersionConsole Version 1/2
Additionally, there is a 33% chance in Expert mode that the chance of the trophy drop will increase (1/4 -> 1/3, 1/3 -> 1/2, 1/2 -> 1/1). Factoring all these chances together at minimum and maximum waves results in the chance of the trophy dropping being 4.17% - 12.5% / 6.25%-100% Desktop VersionConsole Version.

Tips[edit | edit source]

  • Note that his Present launch and rocket barrage attacks are highly inaccurate.
  • If you use wings you can fly over him back and forth and make it harder for him to hit you with the chain gun and the rocket barrage.
  • If you have obtained the Razorpine and Golden Shower then you can hit him with the Golden shower to lower his defense then fire your razorpine at him. This is highly effective with Spectre armor as it fully heals you no matter how low you are. This seems to be even more effective on the Mobile only.pngMobile version and 3DS logo.svg version because the Spectre Hood still has its old stats, which increases magic damage, instead of lowering it.

Trivia[edit | edit source]

  • "Santa-NK1" is a play on the portmanteau of Santa and Tank, "Santank." The name used when the enemy was first announced.
    • The image in the game files used for when the face is ripped off uses the name "SantaTank.png."
  • Its arm appears to be a large Chain Gun, an item which it sometimes drops.
  • On the Mobile only.pngMobile version, Santa-NK1's face does not get torn off when its health is low, but instead will tear off upon death.
