[Autumn]

I've always been under the impression that Invocations should have a damage breaking threshold, what that'd mean is that Invocation would be set at a certain level (Increased MASSIVELY by the Invocation talent itself) which would be your 'damage threshold', it'd be a very generous number that allows people to unload burst damage into an invoking mage in order to potentially save an ally or themselves from certain destruction.

Say the threshold starts at 50 and goes up by 30 per SR of the invocation talent. This would be if you are counting post-mitigation damage, if you want to treat tanks fairly and go for pre-mitigation damage you would need to ballpark for anyone with high DPS being able to shit out roughly 600-700 pre-mitigation damage in a single turn and constitute that as burst.

When that threshold is crossed (IE: Invocation runs out of levels similar to frozen) the status is broken.

No other changes to silence would exactly need to occur if Invocations weren't 100% assured like they are currently.
