Mastery Cave

Warning: Spoilers   This page or section contains unmarked spoilers from update 1.6 of Stardew Valley. Players may want to avoid or be cautious toward reading this article/section.

Mastery Cave
Closed:	Never
Address:	Cindersap Forest
Occupants:	None

The Mastery Cave is an area located in Cindersap Forest. It is unlocked after the player has achieved level 10 in all 5 skills. It can be accessed right after the player reaches level 10 on the fifth skill; there is no need to wait until the next day. Inside, the player finds a letter from Grandpa in the southeast corner, a pedestal in the middle of the cave that reads "The Last Path" and displays the mastery progress bar, and the five pillars, each describing a mastery of a skill.

If the player attempts to enter before reaching level 10 in all skills, a message will display: Only a master of the five ways may enter (X/5), where X is the number of player's max-level skills.

Grandpa's Letter

In the southeast corner Grandpa has left a letter for the farmer. The letter will read the following:

“

“My dear <player's name>, If you're reading this note, you've found the secret room I've prepared for you. Within these walls are tips, recipes, and even some of my most cherished tools... all the very best from the many happy years I spent in the valley. By coming this far, you'll have proven that you possess the skill and wisdom to make good use of these powerful secrets. I hope my discoveries help you in your journey to making <Farm's name> a shining star of the whole world! Make me proud! - Grandpa ”

Masteries

Mastery points that are used to unlock a series of masteries. Each mastery is associated with one skill, and each is represented on a pillar on the cave's back wall. At any time, the player can view the special items and benefits associated with a mastery by visiting its pillar.

Mastery points are equivalent to "excess" skill experience points, above those needed to achieve the initial level 10 skills. They are accumulated only after reaching level 10 in every skill. Farming experience points only contribute to mastery points at a 50% rate, while experience points for the rest of the skills contribute to mastery points at a 100% rate.

Experience points after reaching skill level 10 that were earned playing an earlier version of the game do not carry over as mastery points in v1.6. They are collected and grouped as a single quantity regardless of the skill type associated with the experience, and may be used to award any mastery. A mastery can be unlocked at a pillar only when a sufficient number of mastery points has accumulated. The player may pick which masteries to unlock in any order. Each mastery picked costs progressively more mastery points than the previous one, defining five levels of costs. The player can track the current progress towards the next level in the Skills tab.

The following table shows the costs to unlock each mastery:

Level	Mastery Points Required for This Level	Total Mastery Points Required Through This Level
1	10,000	10,000
2	15,000	25,000
3	20,000	45,000
4	25,000	70,000
5	30,000	100,000

When the player accumulates enough mastery points to unlock a new mastery, the game shows a message saying "You've reached a new level of understanding...". The cave's pillars are then available for unlocking a mastery. Masteries achieved are shown on the Special Items & Powers tab of the player's inventory.
