Re: [RPM] High Energy Cost spells (Example Body of Shadow)
 

Again, Body of Shadows isn't mid-ranged: it's the most expensive ritual that's been published! 'The most expensive option' is in no way a 'mid-range' option.

If you feel that Body of Shadows should be cheaper because you don't see it being worth as much as a ritual that can unavoidably disintegrate someone or curse an entire kingdom or whatever, then you should probably alter the assumptions going into the ritual rather than try and make mid-range casters able to do anything that a 350-point ritual can do.

Re: [RPM] High Energy Cost spells (Example Body of Shadow)
 

That's another really good point and a important one. For 348 energy you can get a spell that does 15d-1 corrosion damage (for a internal damaging spell) or one that does 44d+1 corrosion damage (for a external one). That is a LOT of damage, almost enough to wipe out a normal HP 10 person for the internal damage and more than enough to take out a car for a external one. For the same amount you could call a horde of undead to do your will or give your self DR 68 for a hour, or any other number of really crazy, amazing things. A "mid-range" spell is about 100 or so energy. It's tough to pull off, but possible and allows you to do some amazing things. I say this as a GM and a game designer with more experience using RPM than just about anyone else who frequents these boards. I got to playtest MH and thus got a look at RPM before it was ever released, that was in 2010. I've used RPM in damn near every setting that has magic and I've spent time playing with it in nearly every way you could think of since then.

Sorry about this. I started my reply before your edit in post 5 and before Langy and yours following posts and my post ended explaining what didn't need explaining...

In the games where I used RPM, I did what other suggested above : playing with greater/lesser effect to favor/discourage some rituals.

Enchanting MIGHT be an exception, but it depends upon the conquences for a failed rolled.

Re: [RPM] High Energy Cost spells (Example Body of Shadow)
 

Nope, it's not unless the GM house rules it otherwise.

Now, there is a optional rule that could be used if the GM is willing: the Speedy Enchantment perk from GURPS Thaumatology: Magical Styles, which gives access to the Time and Reliability (GURPS Thaumatology, pp. 108-109). It might be balanced as a perk depending on what your campaign is. In my current campaign I charged a 10-point Unusual Background to even enchant anything in the first place, though those that can use the rules for the Speedy Enchantment perk.

I was actually talking about the bonus for working under unstressfull conditions, I don't understand why you brought the time spent rules into things

Re: [RPM] High Energy Cost spells (Example Body of Shadow)
 

Presumably because it's a clear example of a bonus for "unrushed" use. Considering the dangers inherent to RPM casting, I would be hesitant to give any "unstressful" bonus.

Re: [RPM] High Energy Cost spells (Example Body of Shadow)
 

Because they're related, and because magic is never going to be a "easy" or "mundane" task. I figured I'd knock out both subjects in one post. Again, you're manipulating dangerous energies to perform supernatural feats - nothing about that says it's not stressful. You screw up and bad things (literally) happen. Of course, in your games you can Rule Zero it and say otherwise and that's fantastic! Wonderful, tell us how it plays out. :-) But normally? No.

Re: [RPM] High Energy Cost spells (Example Body of Shadow)
 

I see the main problem of OP here not in the pricing or skill in general but in either underestimating of spell effect or its overpricing. I'm inclined to second since i don't see how this spell can be abused, especially in common magic campaign.

Re: [RPM] High Energy Cost spells (Example Body of Shadow)
 

Pretty close to this. I see I have miscommunicated and made a lot of people think that I want mid-ranged casters to be capable of casting 350 energy cost spells. That is not the case. It is an issue with the cost of certain spells, such as Body of Shadow, that I am having the issue with and that I feel this spell is one that is more expensive than it need be for a common magic campaign.

Again, I am not saying "Mid range casters" should be able to cast 350 point energy spells - I am saying that Body of Shadow feels like a spell I want mid-ranged casters to be able to cast. There is a subtle difference.

Dropping the multiplier from costs and making it a penalty to the skill roll seems to be working for me pretty well during the re-pricing. I'm sure if there are any unpleasant surprises in doing this, i'll find out when i run this afternoon.
