Koboldite.

[miner-bob-1960]

is there a way to get Hobgolins to spawn in the 1.8 update or a way to get Kobldite, as its needed for infinity ingots.

Large pastures spawn them over time iirc

[miner-bob-1960]

thay spawn in forest and some times plains biomes, and there is no way to change the biomes as none of the biome changing works.

[chuggafan]

IIRC the witchery biome changing still works, try it

[Messiah7]

Yep, witchery rite of shifting seasons work fine, i change biome to forest and growing some trees, but no one hobgoblin for 5 hours (biome like a circle ~5x5 chunks)

UPD: I checked a lot of biomes (forest and plane type), but hobgoblins not spawn
