Growing Dungeons and Shining Trees, aka Twinkle Trees in Rune Factory 4

I really love Rune Factory 4.  I think that a real effort was made to add new surprising options to the game while retaining all the aspects of Rune Factory that die-hard fans like myself love and expect from any Harvest Moon or Rune Factory game.  While I have been slightly disappointed in some of the recent Harvest Moon games, finding them too arduous in some respects without being more exciting or interesting, Rune Factory does not disappoint.

Some of the new options involve Farming.  One can grow a Dungeon for example, from a special Seed obtained from an extraordinary monster who looks like a cute little Chipsqueek and initially can be found only between the first and fifth days of any Season.  Once you have found him, however, the location of his lair will appear on the map and the airship will 'remember' it and you can visit any day of the season.

Other wonderful new magical Seeds include the Shining Tree or Twinkle Tree and the Sword and Shield Crops.

Requests are a fundamental part of Rune Factory 4 as they have been in all Rune Factory games.  Eliza here is the one to give Requests.  She is a 'person' who once was the Sharance Tree evidently but only Freya can speak to her or recognise her as an individual in the early stages of the game.  You begin with a single Request each day but as you complete Requests, Eliza will allow you to take more.  Freya now is at the point where she can complete up to three Requests each day.

One of Eliza's Requests is to chop down a Shining Tree.  The Shining Tree is named the Twinkle Tree when it is grown in the field.  A random number of strokes with an Axe is required to chop down a Twinkle Tree and only a fully mature Twinkle Tree can be cut.  It broke my heart to chop down a Tree that took so much time to grow!  Luckily I did not save the results the first time because by not doing so, I was able to discover that the number of strokes (and therefore Lumber) as well as the actual Items you obtain when you cut down a Twinkle Tree is RANDOM.  I went through it a number of times to see how different the results could be.  In some cases, all I received was Lumber.  In other cases, I received 1 of the rare Glitta Augite stones.  In other cases, I received 2 Glitta Augite Stones with over 30 Lumber.  I never received more than two, however, so I finally saved with two Glitta Augite Stones and 36 Lumber.  The description of these is:

Glitta Augite: Collectible
  Difficulty: 50
  A strange stone produced by a tree.  Emits strong light.  If used for reinforcing a weapon, extends the range.

The selling value of a Level 5 Glitta Augite is 952G.
At 50 Difficulty, Freya is not strong enough to use it in forging yet, but will do as soon as possible!  She had a bit of luck in the early days of Spring when she found an Invisible Stone and was able to make an Invisiblade with it.  That weapon was far better than anything else she could have made without having unlocked any dungeons apart from Yokmir Forest.

Invisible Stones are a random discovery when using a Hammer on Rocks.  Found first in Yokmir Forest on a number of different screens, Freya was able to find them elsewhere as well later in the game.  Darkness Stones are found in a cave.
