I just realized that there are 4 types of things you can do with an evocation spell, but only two types of focus item bonuses.  You can attack, block, maneuver or counterspell.  The bonuses you get from focus items are only defensive or offensive(whether you choose discipline or conviction).  How do they work related to a counterspell or a maneuver or is it context?  could you apply your defensive focus item to the counterspell? 

I'm finding myself incredibly excited about the DFRPG system!  I have a few questions related to Thaumaturgy that I'm hoping somebody can help me with. 

I've been thinking about a good luck spell that just adds a temporary aspect for a good long duration like maybe a couple hours or even a day.  What would the cost be to add that aspect to a willing person?  Would it be 1 plus the aspect cost of 0 (temporary aspect) plus the duration or would the base have to beat the target skill even if they are willing? 

Is there a general rule of thumb for duration?  is it fair for a base thaumaturgy spell to last an hour if there is an aspect involved? 

Thanks in advance!
