When to Rest vs Upgrade (This Decision Wins Runs) | Slay the Spire 2 Guide

In Slay the Spire 2, one of the most important decisions you make at every campfire is whether to rest or upgrade. Most players default to resting… and that’s a mistake. In this guide, I break down when you should actually heal vs when you should be upgrading, and why choosing incorrectly can quietly ruin your run. You’ll learn how to evaluate your HP, upcoming fights, and deck strength so you can make the right call every time. If you’ve ever wondered why your runs fall apart in Act 2 or 3, this decision is a big part of it. What you’ll learn: - When resting is actually correct - Why upgrading is usually stronger - How to evaluate risk vs reward at campfires - The biggest mistake new players make Subscribe for more Slay the Spire 2 guides, tips, and high-level runs.
