What the game says

Grants [Theostone: Santras's Secret].

The obtained Theostone can be found in the Enhancement menu.

Has a 5% chance to deal 300 Poison damage every 2s for 20s on attack

Effect Activation Cooldown: 1s

Only one Theostone's effect applies when identical Theostones are engraved.

What it’s for

It’s engraved on gear. When you attack, there’s a 5% chance to poison: 300 damage every 2 seconds for 20 seconds, and the effect can’t trigger more than once per second. If you engrave two identical ones, only one counts, so don’t double up.

When you use it, it doesn’t stay in your inventory: it goes to the Enhancement window.

Where it drops

Metabot has no source for it. The unbound version is sold on the Market.
