Ruins of Adventure
Potion of Water Elemental Form
A luminescent blue liquid in a plain glass bottle.
Upon imbibing the potion, the user immediately changes into a water elemental for 1 turn (10 minutes). While in elemental form, the user gains all of the attacks and abilities of a water elemental, though his Armor Class and hit points remain the same. Note that a protection from evil or other effects that specifically ward away summoned or extraplanar creatures does not block a character using this potion. Effects which specifically ward against elementals do work however.
The unconsumed potion glows with a dim blue light. This light is sufficient to read by (if held within 6 inches of the thing to be read).
