Small crystal flask

Small crystal flasks are purchased at town alchemist shops. They are used for storing troll's blood and sea water. Each flask holds 20 doses of its respective contents. To remove the contents from the flask, one must use a glass vial.

Analyze

You analyze your crystal flask and sense that the creator has provided the following information:
 
The crystal flask is a storage device for troll's blood or sea water for use with Animate Dead or Alchemy.
 
You may HARVEST WATER WITH flask while in appropriate rooms to collect sea water.
 
It may be altered, but the alteration cannot conflict with the description when OPEN, CLOSE, or LOOKing at the flask when full or empty.  The metal of the chain may be adjusted to any metal of appropriate rarity that can be inspected.
 
You get no sense of whether or not the flask may be further lightened.
