Potion of Petrification

Potion of Petrification is a consumable that protects the player from physical attacks and all spells, but makes the player unable to perform any action.

Previously known as the Flask of Petrification, several quests and items still refer to it by that name. However, it shares none of the current characteristics of a Flask.

Source
Potion of Petrification is created by Alchemists with a skill level of 300.

The recipe for this item is taught by Recipe: Flask of Petrification is an Azeroth (Eastern Kingdoms and Kalimdor) World Drop.

Historical Notes
This item (prior to patch 3.2.0) was made famous by a video called "God Mode" where a paladin jumped off a building in Orgrimmar and drank the potion and proceeded to scream "KILL ME!!!!!!!...!!!" repeated (on a macro). Then as soon as it wore off he would bubble and hearth. After the fiasco he was reported and a GM responded and talked with Mr. God Mode and he proceeded to smart off to the GM and risked suspension or ban.
