Spell level

From NWNWiki

Spell level is a number between 0 and 9 that defines the spell's relative power. Level 0 spells are also called cantrips, and epic spells are sometimes called level 10 spells.

In spell descriptions, the level is preceded by an abbreviation for the class whose members can cast the spell. The level entry also indicates whether a spell is a domain spell and, if so, what its domain and its level as a domain spell are. A spell's level affects the DC for any save allowed against the effect.
