Stardew Valley Mastery, Books & Trinkets Lab 1.6
Mastery, Books & Trinkets Lab
Plan all five Mastery stars, track every 1.6 book and Bookseller visit, then compare trinkets and budget exact Anvil rerolls without splitting your progress across several tools.
Start from a save or plan manually
Choose the large main save file named like your farmer and save ID. The lab reads Mastery XP, claimed plaques, books, year, season, save ID, skill levels, and equipped trinkets.
Private by design: the file is parsed in this browser and is never uploaded. Only the extracted checklist and settings are saved locally.
Manual planner is ready.
Five-star Mastery route
Mastery XP begins only when all five core skills reach level 10. Stars unlock at cumulative thresholds, and any earned star can be spent on any unclaimed plaque.
Suggested claim order
The selected play focus changes only this order; rewards and XP thresholds stay the same.
Edit the five skill levels
Exact Bookseller dates
The Bookseller visits twice per season. Enter the save ID, year, season, and legacy-random setting to see the two matching dates.
Every readable 1.6 book
Track the 19 books required for the Well-Read achievement, the Queen of Sauce cookbook, five repeatable skill books, and the Book of Stars. Repeat-reading XP changes once all five skills are level 10.
Trinket comparison bench
Compare exact roll ranges and choose by job: damage, control, healing, loot, safety, movement, companion, or cosmetics.
Anvil target budget
An Anvil reroll costs 3 Iridium Bars and finishes after 10 in-game minutes. Calculate the exact chance of seeing a target within your bar budget.
Natural trinket drop chance
After Combat Mastery unlocks the trinket slot, each monster kill rolls a chance based on monster health, monster type, daily luck, Luck skill level, and any source modifier.
Stardew Valley 1.6 rules at a glance
Mastery XP
The cave opens at level 10 in Farming, Fishing, Foraging, Mining, and Combat. Post-cap Farming XP contributes half (with a minimum of 1 per XP event); the other four skills contribute their full XP.
Reading books again
A repeated tagged power book gives 100 XP to its tagged skill. Other repeated power books give 20 XP to each skill. Price Catalogue and Animal Catalogue are exceptions and do not grant repeat XP.
Natural trinkets
Seven natural trinket types are selected evenly after a successful drop roll. Magic Hair Gel is instead bought from Alex at the Desert Festival for 100 Calico Eggs after Combat Mastery.
Reforging
Frog Egg, Magic Quiver, Fairy Box, Parrot Egg, Ice Rod, and Golden Spur can be reforged. Basilisk Paw and Magic Hair Gel cannot. The Anvil recipe itself costs 50 Iron Bars.
