In Warframe’s 1999 update, a new opportunity has emerged for efficient resource farming through a mission type called Legite Harvest. With the right strategy, you can farm millions of credits, relics, and arcanes in as little as two minutes per mission — without the need for Steel Path difficulty. This guide walks you through exactly how to do it.

Why Legite Harvest?

Legite Harvest is fast, simple, and highly profitable. Unlike bounty missions, it doesn’t come with layered objectives that slow you down. The normal mode offers nearly the same rewards as Steel Path, so for efficiency, stick to normal mode.

You’ll be assisted by a kavat named Calamos, and your goal is to locate, capture, and secure a Legite — all while maximizing your credit, relic, and arcane drops in a rapid loop.

How to Run the Mission Efficiently

1. Starting the Mission

• Begin from the Orbiter or back room.
• Avoid bounties — they add extra steps.
• Choose Normal Mode for speed and consistency.

2. Legite Tracking Process

• Calamos starts near the underground cave entrance.
• Help him build progress from 1 to 100 by killing enemies and collecting fog glands.
• Once progress reaches 90/100, move forward toward the next area.

3. Tech Rot Cache

• If the Tech Rot Cache icon appears, complete it first.
• If not, return to search after capturing the Legite.
• The cache requires a biosafe code — the good news is these spawn at fixed locations.

All Known Biosafe Code Locations

To unlock the Tech Rot Cache, collect the biosafe code from set areas scattered throughout the mission tile set. While a full visual list was shown in the original guide, players are encouraged to explore and memorize key locations over repeated runs.

Tip: Share any new biosafe code spawns with the community to help others optimize their routes.
