Les Toxin

Les Toxin is a ranged throwable in the Thief item set that applies 2 Poison stacks from a distance, usable once per battle. It deals no direct damage — the entire value is the Poison status, which ticks each round. Throwing it at the start of a fight maximizes total tick damage; the earlier you apply it, the more turns it has to accumulate.

Being common rarity means you'll see it fairly often. It fits naturally into Thief set or poison-stacking builds, where 2 free Poison from range without consuming a melee slot is a real contribution. In a run not built around Poison it's a minor convenience — useful to throw before closing in, but not a reason to hold a weapon slot by itself.
