[PnP] Enhancement

[Scott Adams]

I'm surprised again by v2 and Richard...

Read abelow especially the NOTE



ENHANCEMENT
     This is used to enhance dead and inanimate material that has 
natural magic value, as determined by the Referee or specified in 
the Natural Magic section.
     Success brings out the enhanced value. Failure destroys 1/2 
the material and does not bring out the enhanced value. Abysmal 
Failure destroys all of the material. Material destroyed in this 
way is destroyed only in the sense that it can never be enhanced.
     The amount of material the Caster can affect with one spell 
depends on the type of material, as follows:
Plant derived or liquid
(EL+1)*2 doses
Gem, metal
1 item
Other material
EL+1 doses (If it is consumed in use).
1 item (If it is not consumed)
     Once material subjected to this spell has been enhanced it 
is enhanced forever. A Dispel/Banish spell can eliminate the 
enhancement. The material is destroyed, as specified above, when 
this is done.


NOTE — Enhancement is not possible without knowledge of the
specific enhancement rites for the material. This knowledge is 
learned educationally. The Referee may allow the characters to 
start with knowledge of the enhancement rites of 1D6 materials. 
Shamans learn 2D6 rites in addition to knowledge of materials 
they gain as detailed in Book One.

With that note.  It adds good balance to the spell.  Means a mage can't just enhance everything they find in the forest.  But my question is does one need a NEW enhancement spell to learn 1-6 more or how much is a "rite".  Can a mage go to a herbalist store and ask the rite for a Diamond from a old guy?  The cost isn't clear.  
One might say a new spell is needed or a factor of the spell or just a simple Knowledge spell?

Interesting to consider but not sure yet which way to go.  What do you guys think (especially Richard if your around?).
