This was a tangent in the DFT1 thread that I felt should be split off here. Here's a repost of what I posted there:
So, looks like we've got $1/FP for "Bound into a magic item to power it," $5/FP for "Bound into a single item belonging to the character, usable for anything," and $33/FP for "Restores lost FP."
These could be simplified into "Enchantment, non-portable," "Item Recovery, non-portable," and "Personal Recovery, portable." What's missing, then, would be "Enchantment, Portable" (loot that can replace FP for Quick and Dirty casting), "Item Recovery, Portable" (an item that can recharge your Power Item in the field), "Personal Recovery, Non-Portable" (results in effects similar to a Very High Mana zone, but without increased Critical Failures - you can cast, instantly recover, cast, instantly recover, and so forth, but only within the temple or whatever), "General Use, Non-Portable" (you can use money entirely for powering a spell, but only within the temple or whatever), and "General Use, Portable" (an item that can be sacrificed in place of FP to power a spell). There might also be a Single Use type (where you can sacrifice money in a temple or an item in the field to cast, say, Fireball, but not another spell) and/or a Single College type (as Single Use, but any spell from the Fire College).
Code:
Type Stationary Portable
Enchantment $1 $33
Item Recovery $5 ?
Personal Recovery ? $33
Single Use ? ?
Single College ? ?
General Use ? ?
Filling in the chart would be a challenge, but useful. There may already be some options - note I've filled in "Enchantment, Portable" by using the suggestion from
The Material Difference (Pyramid #3/66).
