Dear Princess Celestia, I have upgraded the Rainbow Factory!
*THUNDERCLAP*
It has a new, modular structure now! Woo!
*THUNDERCLAP*
...So, it is four differently-functioning buildings now.
-Spectra Extractor now only does the extraction part, but accepts any kind of spinal tissue. Non-pony spines can now be refined into Dull Spectra, and alicorn spines are refined into Brilliant Spectra.
-Essence Distillery accepts the liquid containers with various Spectral Residues from the extractor and distills them into Spectral Essences. Previously this was done in the extractor.
-Rainbow Smelter creates rainbow and dark iron bars. Previously this was also done in the extractor. Now with two new (Dull and Brilliant) kinds of rainbow.
-Rainbow Enchantment Altar can create Brilliant Spectra bars from common spectra bars using Ether Orbs, two per bar.
Brilliant Rainbow has very high value and is now required to create Elementium.
Dull Spectra and Rainbow have low value and are good for individual quarters decoration for non-nobles.
Also:
-Mana Crystals are found everywhere in small clusters and prospected from the special minerals at the Taint Refinery. They can drained of energy to recieve Ether Orbs; you also get a Depleted Mana Crystal for decoration.
-Masterwork fuels (peat and anthracite) have been added.
-Creation of tens of taint-wood logs from a single timber wolf now not possible (probably). Created logs have to be processed into workable taint-wood logs at a rate of 5 for 1.
[UPD] Added all the new stuff to the main entities, tweaked the beast-pony entities. Which should actually *work* now (AFAIR, they haven't worked since Valentine's DF).
This is actually getting close to... dare I say, a release. Only have to make some new creatures that I wanted to add.
Now I'm (kind of) confident that I can get it done before the year's over.
