A new ability has been added to the VISION skill: Pipelist.
Pipelist is much like Elixlist, and received a bit earlier in the skill.

AB VISION PIPELIST gives a bit of information.

It should probably be noted that artifact pipes can in fact be lit,
and can go out, but whether they are lit or out is not relevant - they
can be smoked anyway. Thus, they are marked 'arti' in Pipelist output.

Penned by my hand on the 14th of Ero, in the year 359 AF.
