This item has one problem. It doesn't state what "dissipates naturally" means. Is it one round? Two rounds? Ten minutes? Until wind disperses it? Some clarification would be nice.
I'll drop this here so we all don't have to open our books to discuss this item.
Smokestick: This alchemically treated
wooden stick
instantly creates thick, opaque smoke when ignited. The
smoke fills a 10- foot cube (treat the effect as a fog cloud
spell, except that a moderate or stronger wind dissipates
the smoke in 1 round). The stick is consumed after 1 round,
and the smoke dissipates naturally.
