Romestead: Sacrifice Unlocks Technology and Item Blueprints

Welcome to your go-to guide for unlocking technologies and item blueprints through sacrifices in Romestead. This guide covers the six-tier sacrifice skill tree, which is tied to your altar level. Note that the in-game display shows levels 0, 1, 2, 3, 4, and 6 (skipping 5), but I’ve renumbered them as 1 through 6 for clarity. Below, I’ll break down what each god’s tree offers, focusing on items and upgrades with direct in-game descriptions.

Altar Levels and Skill Tree Access

Altar Level	Requirement	Unlocked Skill Tree Tiers

3	Defeat Cyclops Boss	Tier 5
