Crafting and Using Big Oak Planks and Big Wet Oak Planks
This guide details the crafting processes for 
Big Oak Planks and their wet variant, 
Big Wet Oak Planks, along with their basic uses.
Big Oak Planks
To craft Big Oak Planks, you must first acquire 
Pile of Planks. Four Pile of Planks are combined to create a single Big Oak Planks.
Big Oak Planks are used in two crafting recipes:
- Eight Big Oak Planks are combined with a
Water Bucket to produce Big Wet Oak Planks. - Three Big Oak Planks can be crafted back into one Pile of Planks.
Big Wet Oak Planks
Big Wet Oak Planks are crafted by combining eight Big Oak Planks with a Water Bucket. The facts do not state any further uses for Big Wet Oak Planks.
Pile of Planks
Pile of Planks serves as an intermediary crafting component. It is created by combining three Big Oak Planks. Four Pile of Planks are then used to craft one Big Oak Planks. The facts do not state any further uses for Pile of Planks.
Where these blocks sit in the mod
Bosses'Rise is 86 pages across 46 items and 40 blocks, built on 31 crafting recipes and 8 stonecutting recipes. The block half of that is largely building material won from the mod's five boss structures, which is why plank and decoration blocks appear in a mod named after bosses.
The five structures that supply them
Each structure has its own spacing, and the range is wide:
- Yeti Hideout — spacing 30, separation 25, the most common
- Sandworm Nest — spacing 45, separation 30
- Underworld Arena — spacing 48, separation 40, generated as underground decoration
- Kraken Ship — spacing 52, separation 24
- Dragon Tower — spacing 96, separation 24, by far the rarest
A dragon tower at spacing 96 is placed roughly a third as often as a yeti hideout, so material from it is correspondingly scarce.
Stonecutting is the multiplier
Only 8 stonecutting recipes exist, but they are what turn a single block type into a usable set. Carrying a stonecutter to a cleared structure is more efficient than hauling raw blocks home and cutting them later.
Version parity
Both builds are 2.1.2 and carry identical recipe counts, so nothing here is version-specific.
