A 159

Since the spell description doesn't list a cost for the silver to be used, it is treated as a non-expensive material component and is therefore covered under Eschew Material's benefit.

Note that you still have to trace the circle, you just don't need to provide the material component when doing so. (E.g., you can just draw a finger through the dust.)

Q 162

Following up to Q 159, is drawing the circle considered part of the spell's somatic component and therefore rendered unnecessary if using the Still Spell metamagic or similar effect in conjunction with Eschew Materials to eliminate the need for the material component?
