Dungeon Settlers How to Expand Base — Goddess Tears and Build Space

A Dungeon Settlers how to expand base question has one answer, and it is not a bigger plot of land. Your buildable area is hemmed in by purple Dark Thorn Vine growths, and the only way past them is to purify them with Goddess's Tears. Prima Games lays out the full chain, and a Steam thread shows that the same question confuses new players enough to ask directly.

The Goddess's Tears Chain

Everything routes through one crafted item. Getting there means three research steps and two crafting stations, so it is a mid-game goal rather than a first-night project.

Step	Requirement	Notes
Unlock the research	Dark Thorn Vine Purification	Prerequisites are Basic Alchemy and Staff Crafting
Craft Ceramics	Alchemy Bench ingredients, made at a Kiln	The Kiln comes from Metal Processing research
Make Mana Stone Powder	Convert Mana Stones	Pairs with the Ceramics in the recipe
Craft the tear	Alchemy Bench	Produces a usable inventory item

The prerequisite research for the Kiln is Wood Processing II plus Bonfire, which means the expansion chain sits behind the same wood branch that opens early leveling. That is by design: the game keeps routing you through Wood Processing.

Using a Tear and Farming More

Once you have a tear, using it is deliberate. Prima Games describes adding it to a character's inventory, right-clicking the item and selecting Use, which shows a cross-shaped splash zone. Hovering that zone over the purple vine shows how much area will be purified, and a left-click throws the potion.

Tear source	Reliability	Cost
Crafted at the Alchemy Bench	Repeatable once the chain is done	Ceramics plus Mana Stone Powder
Stone Golem boss drop	Guaranteed, per Prima Games	A difficult boss fight

A short checklist for freeing build space:

• Scatter the splash zone to cover the widest patch of vine before you throw.
• Bank a couple of extra tears before you start a room expansion.
• Push chest loot for Tech Books, since they gate the research chain.
• Consider Dungeon Cores on floor 3 and below only when the party is geared, because they trigger hard fights.

The exact splash radius and Tear recipe amounts are not published by the developer, so treat the geometry as to confirm. The research page covers where Wood Processing and the other prerequisites sit in the tree. A few points worth keeping in view:

• Clear the widest vine patch with each tear.
• Bank a spare tear before starting a room expansion.
• Push chests for the Tech Books the chain needs.
