There's lots to do in Spiritfarer. Whether it's cooking a passenger's favorite dish, rearranging their incredibly messy ship layout or just exploring one of the game's many islands, there's never a dull moment or lack of things to do.

Despite this, Spiritfarer features countless useful items, and it can be difficult to keep track of their uses in crafting and upgrading. This guide will help players see the exact cost of Summer's sanctuary and its three improvements that, when they've all been crafted, will unlock the 'Fully Improved: Summer' trophy / achievement.

How To Build Summer's Sanctuary

Summer is one of the first characters encountered in Spiritfarer. The vegan, science-loving snake brings useful plant-growing advice alongside dramatic mini-games that provide access to Quartz and Aluminium. She'll quickly become players' favorite aunt.

A few hours into the game, Summer will ask the player to build her a sanctuary. This will increase her happiness and complete the 'Laying at the Ley Line' quest. Players will require the following crafting materials:

Item Needed

How to Obtain

12x Oak Planks

  • Cut down Oak trees, commonly found in the starting areas' outskirts.
  • Use an Oak Log on the Sawmill

8x Limestone

  • Mine Limestone nodes, commonly found in the starting areas.
  • Sometimes found in dive spots.

How To Improve Summer's Sanctuary

Whether it's to complete the 'A Cold and Dreamless Slumber' quest or just to do something nice for their slippery friend, players will want to improve Summer's sanctuary. Some required resources are only obtainable after advancing some quests and improving crafting stations, so if players have no idea how to get some of the resources they need, it's worth pursuing some of their other quests in the meantime.

Some crafting stations are required to generate the resources that the sanctuary's improvements use. They are as follows:
