This is one of the main issues that were talked about Deep Aether:
Cloudium's out-of-place obtainment and its upgrading system being too simple.

An argument could be made against these 2 issues, regarding the fact that Cloudium should be tedious to obtain and the Smithing recipe should remain as it aligns more to a Vanilla Minecraft style. However we think that this would not follow Aether's way of doing things, and would feel way too bland for such an important ore in our mod.

• Cloudium World Generation:
  The idea that Cloudium spawns in Aerclouds has not been accepted pretty well by everyone. We're still unsure if we're gonna keep a very similar system but more developed and intriguing for players, or change its generation completely.

• Cloudium Upgrade System:
  This is something that will surely change. Through the use of a new block, or a new iteration of existing ones, we'll make sure it will follow a more unique or at least in-line consistency with Aether's way of doing.
