Edited: I would love to know if croppery as a bug has indeed been fixed, and it is herbalism 2 that is giving the bonus yield.. Just a note, herbs that yield 1 shuck 2, and herbs that yield more shuck 1, with a chance of 2:
Plucking Herbs with Herbalism 2 only:
Purple Flower Seed 2
Gandlevery Seed 1
Rubeweed Seed 1
Hairball Flower Seed 1
Rookswort Seed 1
Silvertongue Seed 2
Yellow Crumb Flower 2
Now, with Herbalism 2 and Croppery 3 (shucking is the same)
Purple Flower Seed 3
Gandlevery Seed 1
Rubeweed Seed 1
Hairball Flower Seed 1
Rookswort Seed 1
Silvertongue Seed 3
Yellow Crumb Flower 3
Now, for the analysis of essence first:
Essence of Gandlevery - Bad, the essence is better used in potions, though it does lower mood, which could have use.
Essence of Hairball - Ok
Essence of Purple - Good
Essence of Rookswort - Ok, but still better used in potions
Essence of Rubeweed - Excellent
Essence of Silvertongue - Good, if under 60 and you want to level faster
Essence of Yellowcrumb - Good, if you still have lots of skills to learn
Now to note, only rubeweed is the only great tincture that happens to be one of the bad harvest herbs, assuming we are talking about the essences at face-value, rather than use in potions. This is at least good news for tinctures, however, they are used in the potions, so:
Analysis of Potions:
Amorous Philtre - This one is very easy to make, given Silvertongue's yields
Charades Potion - Another easy potion, though the buff has been reported to be too short.
Elixir of Avarice - Not overly bad, I am curious how many people desire to use this
Rainbow Juice - Requiring no essences, this one is very easy to make, and has fun effects.
Tree Poison - I am thoughtful of the idea that rookswort being intentionally used to ensure it is harder to get a lot of poisons easily.
Tree Poison Antidote - Gandlevery has a low yield, but at least has a low growing time
Ancestral Spirits - If the Ancestral Lands are ever fixed to be useful at any given time, rather than times when no one is on, this might be worth making. 4 essences make this expensive.
Door Drink - Not overly hard to make, though two are needed to have an effect
Keycutter Tonic - Has anyone found a good use for this potion to rationalize wasting rubeweed essence?
Potion of Animal Youth - 5 essences is a lot, again, the two herbs required have lower growing times
Rook Balm - This has limited function. I have not used this, can anyone comment on how effective it is comparative to cost?
