Fusions can be fused further with other aethers eligible aethers.

Legacy Doppelgangers cannot be fused.

Mercury Fusions Edit

Mercury aethers can only be fused with other mercury aethers of the same breed.

Note: According to Onyx, if two different breeds have the same Mercury colors, then those two breeds can be fused as well. For example, Rainbow and Fluttermoth Haers can be blended with Rainbow and Fluttermoth Ocelas. This hasn't been tested so far.

Silver Fusions Edit

Silver doppelgangers can be fused with any other silver doppelganger, regardless of breed.
