Eschew materials works for all casting classes and is a feat characters may select at level one. It gives characters an "Eschew Material" toggle on their class radial sub-menu. When toggled on, component materials on your person will be depleted as normal, but in lieu of their presence, character experience will be deducted based upon the component value.
This feat differs from the Dungeons and Dragons 3.5 feat by the same name. Material components over one gold piece in value, which includes nearly all of those found in the Lands of Intrigue, are still affected by use of the Eschew Materials feat on the Knights of Noromath server.
