Key Points
Terrariums’ first limited-time event runs from October 24 to November 7, 2026. Nightmare axies and accessories bring extra Atia’s Flame throughout the event.
Each Nightmare part adds 200 Flame, each Shiny Nightmare part adds 300, and a Nightmare body adds 200. These bonuses stack.
Nightbloom, Eyewyrm, and Bloodmaw add bonus Flame too. Pair them with a Nightmare part or body for a stronger accessory bonus.
Lunacians, your Nightmares have work to do.
Terrariums: Halloween 2026 begins October 24! Our first limited-time event puts Nightmare axies and accessories at the center of your setup, with two additional boosts to Atia’s Flame.
Even one Nightmare part can make a difference. In the example below, a fully evolved axie goes from 84.8 to 284.8 Flame, an increase of about 236%, from a single Nightmare part.
Check your collection. Halloween gives your Nightmares more power to bring to the Shrine.
Here’s what’s happening:
Nightmare Axie Boost
During the event, Nightmare parts and bodies add a flat amount of Flame on top of your axie’s existing boosts:
Nightmare Part: +200 Flame per part
Shiny Nightmare Part: +300 Flame per part
Nightmare Body: +200 Flame
Every qualifying part counts, and the bonuses stack. Nightmare accessories can add another event bonus, with a stronger boost when equipped on an axie with at least one Nightmare part or body.
A single part can also change what an axie contributes. Take a fully evolved axie with one Nightmare part, five normal parts, a normal body, and zero accessories:
Base Atia’s Flame: 40
Evolved Part Boost: 44.8
Nightmare Axie Boost: 200
Total during Halloween: 284.8 Flame, up from 84.8
That’s about 3.36× its usual Flame for the event. The bonus is a flat addition, so its percentage impact depends on the axie’s starting Flame.
Nightmare Accessory Boost
Bring your Nightmare accessories into the mix. Three accessories qualify:
Nightbloom: Ground
Eyewyrm: Air
Bloodmaw: Cheek
These accessories keep their usual Flame contribution and receive an additional event bonus. The axie wearing them determines the size of that bonus:
Zero Nightmare parts or body: the additional bonus equals their usual accessory Flame contribution.
At least one Nightmare part, Shiny Nightmare part, or Nightmare body: the additional bonus equals 3× their usual accessory Flame contribution.
For example, Nightmare accessories that normally contribute 18 Flame add another 18 on an axie without Nightmare traits. Equip them on a qualifying axie, and they add another 54 instead.
Including their usual contribution, those accessories provide 72 Flame instead of 18. That’s 4× the Flame from those accessories during Halloween.
Pairing matters. One qualifying Nightmare part or body activates the stronger accessory bonus.
Put Both Boosts to Work
The two Halloween boosts add to your axie’s existing Flame:
Base Atia’s Flame + Evolved Part Boost + Accessory Boost + Nightmare Axie Boost + Nightmare Accessory Boost
Here’s how they work together on a fully evolved Mystic axie with four Nightmare parts, one Shiny Nightmare part, and a Nightmare body, equipped with Nightbloom, Eyewyrm, Bloodmaw, and Tristar:
Base Atia’s Flame: 1,000
Evolved Part Boost: 700
Accessory Boost: 22.5
Nightmare Axie Boost: 1,300
Nightmare Accessory Boost: 54
Total during Halloween: 3,076.5 Flame, up from 1,722.5
That’s about 79% more Flame from the same axie and equipment during the event. Tristar contributes to the usual Accessory Boost; the three Nightmare accessories supply the Nightmare Accessory Boost.
Get Ready for October 24
