Hi! I've been seed-hunting a lot for the legendary Modified Jungle Edge biome (or Jungle Edge M before 1.13) recently, and I've found quite a few of these little gems (they really are quite little). This is one of the favourite seeds I found, which features a very large MJE biome near(ish) to the spawn point.
MJE coords: (-540, 760)
The biome is larger than average (see the attached amidst map) and can be divided roughly into 3 connected sections:
- The western area is composed of some relatively flat fields and could easily be mistaken for a regular Jungle Edge. There's also a pond here.
- The central area (my favourite bit) is very typical of signature MJE terrain, featuring multiple steep cliffs and 'canyons' in between (I've uploaded an image of this part of the biome to the Minecraft Wiki)
- The eastern area is similar to the western part, with fields that rise up in gradual hills.
As per standard MJE generation conditions, the biome borders a Swamp Hills biome.
Since AMIDST has just been updated to work with 1.13.1, and they fixed the issue with the spawnpoint marker, here's a more zoomed out view of my seed including the spawnpoint. The player icon is in the MJE.
Also if anyone has found larger MJEs than mine, please post the seed below, I'd love to check them out! So far this is the biggest I've seen.
