Underworld Terraforming [_]

[CrUsHeR]

Honestly I'm still a bit confused about the underworld terraforming, more precisely about the Bedrock tunnels which prevent annexation.

Technically it seems that Bedrock counts as both Mountains and Desolate? Some of them also contain ice or snow.

Post your first hand reports about actual usefulness of the available terraforming spells.

1. Create Forest

Adds Forest feature to target friendly or unowned province. Turns into Mushroom Forest Underground.
Doesn't work on Mountains, Desolate, Lava or Ice terrain.

This means that Bedrock and Icy caverns cannot be terraformed? For me this only worked in regular provinces (which already allow quarry or hut)



2. Restore the Land

Adds grasslands feature to target friendly province. Works on Desolate terrain. Turns into Fungus Fields Underground.
Doesn't work on Mountains or Ice terrain.

Only works on owned provinces, so this one's not an option



3. Earth Shatter

In target Province:
Adds the Rocky feature. Can destroy Mountains.

Now this one actually works on Bedrock - about half the time.
There are a lot of Bedrock tunnels where it doesn't work, though. I believe it doesn't work if the province has water/lava/ice on it or next to it?



4. Flash Freeze

Target Province:
Is altered to Arctic terrain.

Never took this tome. Any first hand reports on usabilty?

Create Forest was my go-to in the last underground playthrough I did. It can be used to turn the narrow pathway 'provinces' into something you can actually annex so you can expand further.

Then there is destructive regrowth and enchanted bloom, which don't seem to have any terrain restrictions, but I haven't used those yet.

Yeah so far it's been a problem that the games escalate into chaotic war sooner or later, so there's a lot of stuff where i no longer pay much attention, like the terraforming.

As mentioned above, the Earth Shatter spells seems like the most useful from all options, as it also works to destroy mountains on the surface. It also adds the rocky feature to any province which normally cannot be annexed or only allows a hut.

Though i couldn't figure out why certain Bedrock tunnels don't allow it. The province is visible, it has the exact same province description as any other tunnel, yet sometimes it works and sometimes it doesn't.
