mining age with no mobs

[zaekeon]

what's the mystcraft symbol combo that gives you no hostiles?

is it mushroom biome or mushroom island or lots of mushrooms? seems like mushroom biome is twilight forest so maybe that's okay?

I know Mushroom Island is the one with no mobs... not sure about the others you listed as I haven't tried them yet.

follow my instructions to the letter:
Mushroom Island Biome, Single Biome, Standard Terrain Generation, Full Length, Normal Sun, Full Length, Normal Moon, Normal Stars, Normal Weather, Bright, Clear Modfiers.

Mushroom islands and ice ocean will do that. Noon sun and zero length will do that as well. More or less.
Keep in mind all of this will only stop surface spawning.
The mods creator has mentioned something about mob controlling symbols.
All creepers or something like that. But I don't know if that'll include a no mobs symbol.
