Born in Chaos Grave Structures and Spawning Biomes
This guide details the various grave structures found in the Born in Chaos mod and the biomes where they naturally generate. Born in Chaos introduces numerous new structures, including these graves, as part of its goal to diversify and complicate survival by adding various opponents and challenges.
Grave Petasi
The Grave Petasi structure can be found in snowy plains and snowy taiga biomes. The game attempts to place this structure once per 90x90 chunk region. Each generated Grave Petasi will be at least 10 chunks away from other instances of this grave type.
Grave Plug
The Grave Plug structure generates within dark forest biomes. Placement attempts occur once per 100x100 chunk region, ensuring that each Grave Plug is at least 10 chunks apart from others.
Grave Rotborne
The Grave Rotborne structure appears in snowy plains biomes. For this grave, the game attempts placement once per 97x97 chunk region, with a minimum distance of 7 chunks between each generated instance.
Grave Somfunambulist
The Grave Somfunambulist structure can be discovered in forest biomes. The game attempts to place this structure once per 100x100 chunk region. Each Grave Somfunambulist will be at least 12 chunks apart from other generated instances.
Grave Tem 187
The Grave Tem 187 structure generates in both sparse jungle and savanna biomes. Placement attempts for this grave occur once per 115x115 chunk region. A minimum distance of 6 chunks is maintained between each Grave Tem 187.
Grave The Gentleman Frog
The Grave The Gentleman Frog structure is found in mangrove swamp biomes. The game attempts to place this structure once per 65x65 chunk region. Each generated Grave The Gentleman Frog will be at least 6 chunks away from other instances.
Gravecarrionexe
The Gravecarrionexe structure appears in old-growth spruce taiga biomes. Placement attempts for this grave occur once per 100x100 chunk region. A minimum distance of 9 chunks is maintained between each Gravecarrionexe.
Grave spacing, and why some are so hard to find
The graves are not placed on one common grid — each has its own spacing, and the range is wide:
- Grave D 4Rk Devil X — spacing 60, separation 6, the most common
- Grave 2003Wise — spacing 95, separation 10
- Grave 2 Dling — spacing 96, separation 9
- Grave Darktitan — spacing 105, separation 15, the rarest
A spacing of 105 against 60 means the Darktitan grave is placed with roughly a third the frequency of the Devil X one. If you have found several of one kind and none of another, that is the reason.
Reading separation as well
Separation matters as much as spacing here. Grave Darktitan has both the widest spacing and the largest separation at 15, so two of them are never close together. The Devil X grave's separation of 6 means the opposite — where you find one, another may not be far.
The mod behind them
Born in Chaos is 351 pages across 240 items and 111 blocks, with 31 structures in total and 127 crafting recipes. The graves are one family within a much larger structure set that also includes dark towers, clown caravans, farms and firewells.
Version parity
All recipe categories carry identical counts on 1.21.1 (1.7.6) and 1.20.1 (1.7.5), so nothing about the graves differs between builds.
