Mineral Vein

__NOTOC__
The Mineral Vein provides a combination of mining and excavation activities. Every earth day, you can gather from your mineral vein a set number of times, which increases per upgrade.
*Upgrade key items can be purchased from Zenicca for bayld, or from Skipper Moogle for gil.
*Upgrades become available depending on the total number of real-life days you gather from your mineral vein.
Mineral Vein #1: available in your Mog Garden after completing Mining Missive.
Mineral Vein #2: Gained upon reaching rank 3. The boulder face will appear worn away, granting a second mining point.
Mineral Vein #3: Gained upon reaching rank 5. A second boulder will appear to the left, granting a third mining point.
Mineral Vein #4: Gained upon reaching rank 7. The left boulder's face wears away to reveal crystals, granting a fourth mining point.
==Serums==
*Serums will persist for 7 harvests.
Serum 	Effect
Rockoil 	"Multiple Excavations" takes one try
Stone Serum 	Increases yield
Vein Serum 	Occasionally grants free mining attempts
Auserum 	Yields 1 precious metal
Smelting Serum 	Yields 1 metal
Coalition Serum 	Yields 2 metals or precious metals
Monarch Beetle Saliva	Yields 0-3 Antlion Spirits
==Yields==
Every mining attempt yields items in the following order:
#1-3 items, randomly chosen from the Metals + Biominerals lists or the Precious metals + Biominerals lists. This choice is invisible to the player, and is specific to the particular vein mined. E.g., if you gather from Mineral Vein #2, you will only get Mineral Vein #1 and #2 items, never Mineral Vein #3 nor #4 items.
#Bonus yield from serum.
#Bonus yield from Yeestog. Instructing Yeestog to "make mining easier" will yield 1 additional item.
Choosing "multiple excavations" will repeat the action until it changes (the attempt's random choice changes from "metals" to "precious metals" or vice versa). As a consequence, an initial "multiple excavations" action that digs up "metals" will cause the next "excavation" action to dig up "precious metals", and vice versa.
Any item slot may yield a crystal instead.
Instructing Yeestog to "repair the tools" will occasionally grant free mining attempts.
