Petrified

From NWNWiki

A petrified character has been turned to stone and is considered unconscious. Though a petrified creature has the visual appearance of standing up, it is in fact still susceptible to prone conditions such as knockdown.

Petrification is one of the more insidious effects because there is no immunity that protects from petrification itself. The only defenses against this effect pertain to the spell or ability that inflicts it, such as a saving throw or immunity to the spell/ability in question (e.g. immunity to the specific spell flesh to stone).

[edit] Common NWN application

The standard BioWare use of the effect contain some scripted provisos as to its use. Among them are:

• The effect is not used against some creatures by their appearance. These include golem appearances, skeletal appearances, elemental appearances, appearances of creatures that would naturally be able turn things to stone (medusa, basilisk, gorgon, and cockatrice), non-corporeal creature appearances, and a few others (battle horror, shadow dragon, animated chest).

• On hard-core or higher game difficulty the duration is permanent and the death GUI will pop up for player characters.
