You may replace costly material components with a special focus item.
Prerequisite: Eschew Materials
Benefit: To use this feat, you must create – or have an artisan create for you – a personalized and distinctive valuable non-magical item that you can hold or openly wear while casting spells. You must own this item for at least 1 week before utilizing it.
So long as you hold or wear the item, you may cast spells without needing its material components if the cost of the components is less than half the cost of your signature focus. You cannot spend more than 25 gp times your caster level when creating or buying a signature focus. You can create or buy a new signature focus at any time you wish.
