I will provide a set-up situation and then ask how it works. I have a Chronicles of Darkness 1e character within the Mage: the Awakening source. He has Intelligence 4, Crafts 3, and Prime 4.
He casts the spell Phantasmal Arms as a rote, using the above attribute, skill, and arcana. This gives the spell a 11d10 dice pool. Though unlikely, assume every d10 rolled is a Success. With 11 Successes, I can place each Success into an Equipment bonus.
For Weapons, this is simple, as I place Successes into Equipment bonuses on a 1 for 1 basis, but what happens with the Potency of the spell? Do I need to then split the Successes between the Equipment bonus wanted in the weapon and the Potency I want the spell to have?
If so, then what about armor? Do I need to then split the Successes between Standard Armor and Firearms Armor, and then the Potency of the spell?
