Purple Chalk

There are four types of chalk in Ars Magica that allow one to scrawl a mark on the floor in certain circumstances. In order to work, they must be written on a 3x3 flat area. Some marks must be accompanied by pillars of a specific type in order to function.


 * Red Chalk is used to create a Dark Nexus, which converts mobs into Raw Essence
 * White Chalk is used to create a Light Nexus, which draws Raw Essence from the environment
 * Blue Chalk is used to create an Essence Nexus, which converts items into Raw Essence
 * Purple Chalk is used to create a Null Magic Rune, which prevents spells from being cast in its vicinity.
