Wooden Triangle Ceiling

A triangular wooden ceiling

ARK: Survival Evolved lists this building piece as the Wooden Triangle Ceiling; in ARK: Survival Ascended it is the Wood Quarter & Triangle Ceiling. Its in-game text: "A stable wooden ceiling that insulates the inside from the outside, and doubles as a floor for higher levels." The ARK Wiki counts it as the first triangle ceiling that can be unlocked. Like any ceiling it keeps the elements off what lies below and adds to hypothermic and hyperthermic insulation.

Placing it

It can be set on a Foundation, a Pillar, a Wall or another ceiling. After the first one is down, further Wooden Triangle Ceilings snap along its edges so they line up, as long as there is room. Support has limits: a ceiling needs a foundation or pillar nearby and can extend at most 2 ceilings along the x or y axis, or 1 ceiling diagonally, from a wall or from a ceiling right over a foundation or pillar it is connected to. Ceilings at the outer ends of such a layout cannot hold walls.

Unlocking and crafting

The engram unlocks at level 11 for 6 engram points, and the piece is crafted in your inventory. A craft takes 4 seconds, gives 5.56 XP and needs:

• 30 Wood (or Fungal Wood)
• 8 Thatch
• 5 Fiber

Each ceiling weighs 2 and up to 100 stack together, 200 for a full stack. Our records count 54 crate types that can contain it, among them the Aberration Green crates on Aberration and Valguero and the Astraeos Blue crates.

Damage and collapse

The game treats it as a wooden structure: bare hands, stone weapons and ranged attacks without explosives cannot hurt it. A number of aggressive creatures cannot damage it either; the wiki's list includes the Titanoboa, Sabertooth, Raptor, Direwolf and Thylacoleo. If the ceiling is destroyed, any piece it supports is destroyed too, and demolishing it gives no refund for those extra pieces.
