Shadow Spells included prices for buying the different Reagents, where Street Grimoire left you solely with the base costs for the creation process.
I got the price and availability list into Shadow Spells, because there was assumptions where they would have gone in Street Grimoire and it didn’t come to pass.
More Usefulness to Alchemy (Orichalcum and Advanced Reagents)
For me there was two reasons why there wasn’t any rules around orichalcum and advanced reagents. 1. For my chapters I went way beyond my word count so I was hoping to defer the rules to the artificing chapter. 2. Things happened. And you can see there is some things lacking in Street Grimoire.
I’ll Preface this with “These are not Official Rules in Shadowrun 5th Edition” but here’s my proposed rules if you would like to playtest them in your games. Always looking for feedback (I’m the only magician in my game at this point).
REAGENTS USED WITH MAGIC
Per Dram
Raw reagents
Reduce drain by 1 for rituals
Raise the limit by 1 for all magical tests.
Create temporary Ritual Circle (SR5 p. XX)
Refined reagents
Reduces drain by 2 per dram for alchemy
Raises limit by 5 per dram for all magical tests.
Create Magical Compounds (SG p.219)
Create Radical Reagents (SG p.210)
Radical Reagents
Reduces drain by 2 for artificing
Reduce object resistance/opposed force by 2 per dram for rituals or alchemy.
Adds 1 additional service when summoning a spirit (Max 1)*
Adds 1 additional service when bonding a spirit (Max magician’s Magic rating)*.
No Force limit for all magical tests.
Reducing Spirit Index (SG p.207)
Create Orichalcum (SG p.210)
Create Fetish (SG p.212)
Create Inanimate Vessel (SG p.214)
*Note that if the magician gets no services in the test, then the additional services are lost.
Orichalcum
No Force limit for all magical tests AND one of the following:
Reduces object resistance/opposed force by 2 per dram in artificing and conjuring.
Increase Magic rating by 5 when calculating effect with the use of sorcery.
Doubles the # of services achieved when summoning or bonding a spirit
Bone Reagent
With the sacrifice of a victim, a magician can condense the very essence of the subject into a bone. It’s a powerful reagent that resists being created (Same as resistance with a living vessel preparation). IF successful, a bone reagent’s potency is equal to the essence (round down) of the subject. Creation of a focus with a bone reagent, reduces the drain by the potency value. Bone Reagents are special and aren’t recommended for use with mere sorcery, conjuring, or alchemy. Such uses do allow for the potency to reduce drain, but it incurs a witch’s mark (SG p.XX) plus more. A disenchanted focus containing a bone reagent does not destroy the reagent. While physical damage can destroy it, the magic it contains becomes a haunt (SG p.XX) that can last for months or years. A proper way to dispose of a bone reagent is with grave binding ritual (force equal to the potency of the bone reagent). This releases the contained essence.
Max Limit to # of reagents used
Excluding raw, a magician can only add up to his magic rating in reagents of any combination in a given magical project. Also remember that all reagents are consumed at the success or failure of the magical project.
