RPM Blocking Spells/Instant Gathering

[JulianLW]

Cool. I wonder how Christopher Rice feels about -10 for one-turn casting like this? He seems to be the RPM Guru around here.

And another question, while I'm asking....

How does this work? A flat bonus for anyone with the talent, whatever level? Or +2/level (which seems excessive to me).

What would be other reasonable options for an alternative benefit for Natural Caster? Having +1/level reaction from other casters seems excessive to me, especially if you allow levels higher than 4.
