Characteristics
Overview
A tea that removes some radiation.
The cleanup tea. You come out of a monument with radiation still in you, and this takes some of it off, so you are not limping home while it chews at your health. It does nothing against radiation you have not picked up yet; the protective one is the Advanced Anti-Rad Tea, drunk before you go in.
The ladder runs from the basic Rad. Removal Tea to this one and then the Pure Rad. Removal Tea, each step mixed at the Mixing Table from the one below. One honest oddity: all three share the same description, a tea that removes some radiation. You would expect the higher tiers to clear more, but the text does not promise it, so test it on your server before you spend a stack of basic teas on the upgrade.
Tip
Drink it in the bushes on the way out, not back at base. A long walk with radiation on you is a long walk at lower health, and that is exactly when roamers find you.
Next to anti-radiation pills it has one big upside: you make it yourself instead of hoping a crate drops some. The pill pack warns about dehydration, while the tea's text says nothing either way.
