What Rules Apply to Eversmoking Bottle

[Cloudyshine]

The description says that the smoke is totally obscuring vision, implying that it gives total concealment. But the smoke rules in environmental only gives 20% concealment. On the other hand, the spell Fog Cloud says the following

Quote:

The fog obscures all sight, including darkvision, beyond 5 feet. A creature within 5 feet has concealment (attacks have a 20% miss chance). Creatures farther away have total concealment (50% miss chance, and the attacker can’t use sight to locate the target).

I think the latter better represents what the Eversmoking Bottle's description implies, but I wonder if there's any other rules out there or if I missed something.

Since the Eversmoking bottle uses the pyrotechnics spell in construction, I'd use the smoke version of that spell.

The Eversmoking Bottle says it makes everyone in the cloud Blind, and gives Total Concealment to everyone in the cloud.

'Bottles are made with the Pyrotechnics Spell, which can also grant Total Concealment and inflicts Blindness.

All sight, even darkvision, is ineffective in or through the cloud.

I think it would be a stretch to interpret that some other way.

Use the item description. Magic items often do things differently from either natural rules or their prerequisite spells. Think of it as extra-thick smoke.

There is table variance on this subject.

At my table, I implement it with smoke rules from Core.

Smoke Effects

A character who breathes heavy smoke must make a Fortitude save each round (DC 15, +1 per previous check) or spend that round choking and coughing. A character who chokes for 2 consecutive rounds takes 1d6 points of nonlethal damage. Smoke obscures vision, giving concealment (20% miss chance) to characters within it.
