Eschew Materials [General]
You can cast spells that has a material components.
Benefit: You can cast any spell that has a material component costing 1gp or less without needing that component. (the casting of the spell still provokes attacks of opportunity as normal.) If the spell requires a material component that costs more then 1gp, you must have the material component at hand to cast the spell, just as normal.
