So I've been searching around for several days now without any luck, but am very interested to know exactly how the different skills (Farming, Foraging, Fishing, Mining, Combat) work. The wiki pretty much mirrors what the game tells you outright; that each skill level gained increases your tool proficiency for that skill (reduces the energy-per-use for the associated tool by 0.1), gaining certain skill levels unlocks new crafting recipes, and each skill level of Combat grants +5 HP. One other point that seems universally agreed upon is that increasing your fishing skill also increases the length of the green fishing bar. However, outside of these effects, there are a lot of speculations, rumors, and conflicting information out there. This old reddit post seems like a good starting point for finding out information, but half of all the claims made in it are admitted to be guesses/conjecture. To take the Farming skill as an example, some people claim that it affects your harvested crop quality. The Crop Planner has a slider to show the exact % of gold/silver quality chance with each Farming skill level. However I've also heard people claiming that Farming Skill level has no effect crop quality level. Additionally, how would this interact with Basic/Quality Fertilizer? Does the fertilizer override any effects of your Farming Skill level, or do the two stack together somehow? Essentially I'm looking for a breakdown of the effects of each of the different skills, since in at least some cases (Fishing), it appears they can do more than just reduce energy usage. I'm especially curious because right now some of the food buffs seem to make no sense. Looking at Farming Skill again as an example, let's assume that the only effect of the skill is to reduce watering can & hoe energy usage by 0.1 per level. The food "Farmer's Lunch" gives a +3 buff to Farming Skill for 5 1/2 minutes, which should mean that it reduces hoe & watering can energy use by 0.3 each. This seems to imply that the intended use for "Farmer's Lunch" is right before using your watering can / hoe a bunch, which for most players is done right at the start of the day, when their energy bar is full. However, "Farmer's Lunch" also restores 200 energy when eaten. This means that, assuming your energy bar is already full, and unless you are going to use your watering can / hoe more than 666 times in 5 1/2 minutes (200 / 0.3 = 666.667), you are better off eating the "Farmer's Lunch" after you do all your farmwork, since you will wind up with more energy in the end. And in that case, you may as well eat any food which provides +200 energy, since you aren't using the buff anyway. The same point applies to all the other food buffs: if all they do is reduce energy usage for their associated tools, but they also restore energy, why not just eat them after doing your work, or eat any normal food after doing your work? The exception would be the + Fishing skill food, assuming that the Fishing Skill does indeed increase the length of the green fishing bar, which would make fishing easier. I'm just confused now since if all the "+ Foraging Skill" foods do is reduce the energy use of my Axe by 0.1~0.3 per swing, it's completely pointless to eat them, but if they did stuff like increase quality of harvested forage plants, etc., it might be worthwhile. tl;dr: What exactly do the various skills do when increased normally / buffed by food? Is it merely just a reduction in energy for the various tools, or are there other benefits such as bigger green fishing bar, better quality harvests, etc? Is there a point to using + Skill buff foods if your skill is already at 10? And if Farming Skill does affect crop quality, how does it interact with Basic / Quality Fertilizer?
