The Coastal Grove

Overview

These lands have been underwater for centuries, allowing a dense forest of algae to flourish. The surrounding seawater has almost completely cut off the area from the rest of the kingdom, leaving the nearby marshes almost untouched and full of the remains of ancient settlements.

Coastal Grove is exclusive to the Keepers of the Stone DLC.

Effects

Gift of the Depths	After using bait 150 times in your fishing huts, you will unlock the ability to Sacrifice  Algae in the Ancient Hearth to reduce Hostility.
Strider Port	Your settlement begins on the coast of this strange land, near an ancient Strider Port. Use it to send out expeditions in search of blueprints and treasure. However, you will receive fewer blueprints from Reputation.

Resources

The Coastal Grove has an average amount of Fertile Soil and contains the following Resources:

Trees

All trees can be harvested by Woodcutters' Camps to give  Wood. They may also grant additional Resources depending on the biome. These trees have 2 charges each.

Trees	Charges	Bonus Resources	Description
Kelpwood tree	2	Algae 30% +  Vegetables 10% +  Salt 10%	A very flexible, yet extremely hardy plant. It moves in the wind as if moved by sea waves.

Node weighting

Coastal Grove's nodes all have roughly equal weighting.^[1]

Gift of the Depths

Main article: Sacrificing

When you satisfy the conditions of Gift of the Depths by using 150 bait, the description of the biome effect will change to "Your villagers seem to have grown accustomed to this bizarre land. You can sacrifice algae in the Ancient Hearth to reduce Hostility."

Sacrificing  Algae lowers Hostility by 60 per stack.

Strider Port

Strider Port in-game

Strider Port is a special building all Coastal Grove settlements have in the starting Glade. Strider Port serves as a base for Strider expeditions. It acts as a Glade Event that has no consequences or working effects, and can be repeatedly activated. Once it activates, the Strider will leave and the expedition will progress on its own until the Strider comes back to its port. An expedition cannot be canceled once the Strider has left the docks.

In order to use it, you have to provide the Strider and the crew of the Strider with food. The more supplies you choose to provide, the longer the expedition will take and the better your chances of finding a higher rarity treasure.

Strider expeditions alternate between two types: blueprint expeditions and treasure expeditions. Blueprint expeditions give you a blueprint and a treasure chest, while treasure expeditions offer only a treasure chest, but with a higher chance of higher rarity. You can gain a maximum of 8 blueprints this way. Before sending an expedition in search of a blueprint, you can select the building category you are interested in. All expeditions past the 15th are treasure expeditions, and share the 16th expedition's requirements, duration, and rewards.

Strider Port is the only source of blueprints (not as buildings found in Glades) for Homestead, Rainpunk Foundry, and Finesmith.

Expedition supplies

Each level of expedition raises the required amount of all resources by roughly 20%, up to 180% at level 5. For example, the base (level 1)  Algae requirement for expedition №4 is 20. Going up the levels, it becomes 24, 28, 32, and, finally, 36.

Strategy

• Fishing Hut Embarkation is a great pick on Coastal Grove due to how fishing-heavy it is. Embarking with a Fishing Hut also makes going through the Gift of the Depths charges that much easier.
•  Roots and  Vegetables Embarkations are also great picks, since they cover up to 3-4 expeditions worth of crew supplies, with just a few Vegetables from trees.
• The treasure expeditions have a higher chance of higher rarity treasure, so it'd wise to save food on blueprint expeditions, since the blueprint you get is not dependent on the rarity of the treasure and lower level expeditions will end faster.
• Setting up a  Coal Mine is relatively easy on Coastal Grove. This solves all potential fuel issues at the cost of some building materials.
• Accessible  Coal also makes fuel-based Recipes like  Jerky,  Incense, and  Purging Fire easier to sustain.

Trivia

• Every Coastal Grove map is crescent-shaped.
• Coastal Grove is the first biome to be added in a DLC.
• Coastal Grove is the only biome, where you can find all 3 types of fish ponds.
• Coastal Grove along with Ashen Thicket are the only biomes that can generate veins in the starting Glade, with a 10% chance. ^[1]
• At 10%, Coastal Grove has a lower chance to generate Fertile Soil in the starting Glade compared to other biomes.^[1]
