Anti-Rad Tea reduces radiation damage at high-tier monuments. With a Pure Anti-Rad Tea active you can spend longer at Launch Site, Military Tunnels and Missile Silo before radiation eats your HP — though it's a meaningful supplement to a hazmat suit, not a replacement. Like every Rust tea, it follows the standard tier progression: 4 berries make 1 Basic, 4 Basics make 1 Advanced, 4 Advanced make 1 Pure.

Brew at a Mixing Table or Cooking Workbench. The order of berries in the slots matters — check the Berry & Tea Reference if unsure. The Tea Brewery Calculator tells you how many of each tier you can brew from your current berry stockpile.
When to use it
Heavy-rad monuments: Launch Site, Military Tunnels, Train Yard, Underwater Labs. Drink before entering — 30 minutes is plenty for a monument clear with loot run.
What it stacks with
Hazmat suit — Stacks multiplicatively — tea + hazmat lets you stay almost indefinitely
Anti-rad pills — Different mechanic (pills clear current rad, tea reduces incoming)
