GRAIN ROT Tier Lists
Data-informed priorities — not hype-tier hot takes.
GRAIN ROT tier lists on this wiki rank Outpost room upgrades, constructs, and weapons based on demo progression math and co-op extraction outcomes — not arbitrary letter grades for memes. Use these lists when gold is tight and your crew argues about whether cosmetics or stamina matters more.
Tier lists complement guides; they do not replace mechanics learning. Read Getting Started first, then optimize with lists below.
Available tier lists
- Room Upgrade Priority — which Outpost wings to level first
- Constructs Tier List — blueprint value for stats and blocking
- Weapons Tier List — mallet through gun effectiveness
How we tier
Criteria include:
- Run survival impact — does it prevent wipes?
- Gold efficiency — power per Grinder hour
- Co-op synergy — benefits four-player roles
- Demo vs launch — noted when launch features may shift ranks
We revisit rankings after major patches listed on launch features.
Tools integration
Simulate upgrade paths with the Outpost Upgrade Planner before committing scarce gold.
Tier list philosophy on grain-rot.wiki
We rank for extraction success, not community hype. A construct that clips on Twitch but loses runs stays low. A boring stamina room stays S-tier because it saves extracts. Challenge tier lists with your crew’s wipe data — then propose edits via Discord linked on wiki page.
Connecting tier lists to tools and guides
Tier lists tell you what to prioritize; guides teach how to execute:
- Room priority + Outpost Upgrade Planner
- Constructs tier + Artifacts guide
- Weapons tier + Survive the Corrupted
Run this triangle before blaming bad luck for wipes.
Patch-day tier list protocol
After launch patches, wait for two verified crew tests before accepting rumor tier shifts. Hotfix reversals happen. We mark date stamps in titles so outdated lists are obvious.
Solo tier list adjustments summary
Solo players: +1 tier priority on stamina and health, -1 on co-op anchor damage assumptions. Hybrid solo/co-op groups should plan Outpost upgrades for the weakest consistent player, not the carry.
