Stardew Valley Proficiency – What Does +1 Proficiency Mean?

stardew-valley

When you level up Mining for example, the game will state that you get +1 in Mining proficiency. What does this actually do?

Does it decrease the amount of swings needed to smash rocks?

Or does this just mean that you leveled up 1 level?

Though it displays as a whole number, under the covers your character's stamina can have decimal values. Levels in applicable skills reduce, by a fractional amount, how much stamina it takes to use the tool. Here are the ones I was able to figure out.

These skills cause you to use 0.1 less stamina per skill level with these tools:

Foraging

  • Axe

Fishing

  • Fishing Rod

Farming

  • Hoe
  • Sowing a seed
  • Watering Can

Mining

  • Pickaxe

These always use 4 stamina:

  • Milk Pail
  • Shears
