RPM Cost for 1 second casting time?
 

I'm wondering what the cost would be for a 1 second casting time instead of 5 seconds. There are various ways of calculating this and they seem to put the value in the 20-40 point range:

Calculation 1: +4 to casting skill (since you can reduce tiem by -1 per second). This is 16 points plus (other 8 skills as aternative 'powers' at 1/5 cost). Then slap on a -50% limitation, "only for energy accumulation". That comes out to 20.8 points

Calculation 2: As 4 levels of Compartmentalized Mind with an 80% limitation "Only for energy accumulation" it comes to 40 points.

Calculation 3: Working backwards to figure out the limitation on going from 1 second casting time to 5 seconds. This is about two and a half levels of "Takes Extra Time" limitation for -25% limitation. But -25% of what? Well, probably Ritual Adapt and (on average) 4 levles of Magery. A -25% limitation on that is 20 points.

I'm thinking of calling it 20 points and could even break it up as 10 points to make the first roll 1 second and 10 points to make subsequent rolls one second.

Other input/ideas?

Natural Caster 4 (Accessibility, Only for eliminating reduced time penalties, -50%) [30] is the one that PK suggested in a thread and one that I've used pretty much sense then. So about 30 extra points. :-)

Edit: Found the post here from this thread.

This is definately something I am stealing for my Arcana Talent list

Maybe rename it Advanced Ritual Adept or something in order to still allow characters to have levels of (unmodified) Natural Caster?

Re: RPM Cost for 1 second casting time?
 

Yeah, I called it Fast Caster...but I might rename it to something else. Regardless, it's a new advantage.

Probably the most elegant way is just make Ritual Adept a leveled trait with cost [40/70].

Yeah, probably.

Would that be the same cost for reducing casting time (without more skill penalties) in Effect Shaping styles?

Re: RPM Cost for 1 second casting time?
 

You could probably treat it as such.

Re: RPM Cost for 1 second casting time?
 

Ah. I've been just adding another level to Time for each (so, two levels of Path/Book Adept (Time) to reduce Effect Shaping, and three levels for Energy Accumulating). This is rather more expensive, so I'll have to think about whether I want to do this in my settings. How generally firm is this rule (as in, how unbalancing is it to have the cost at ten points, instead of thirty)?
