Greenfire
(Evocation)

Range:  100 yards + 10 yards per level
Components:  V, S, M
Duration:  1 round per 3 levels
Casting Time:  5
Area of Effect:  Special
Saving Throw:  Special

On casting greenfire, a bolt of green luminescence appears from the wizard's fingers, and impacts on the target (a successful saving throw means the bolt missed the target, but it hit somewhere...). From this impact point, a green sphere begins to grow, at a rate depending on the material consumed. Items in this area of effect must save versus disintegration every round. Items that save halt the progress of the sphere until they fail their saving throw. Note: the spell expands for a set time, not to a set radius, so an artifact that continues to save will halt the growth of the sphere for the full duration of the spell.
Rate of growth:
•	200 feet per round in air alone: (not an aerial weapon), but as soon as it hits something solid, it will take one tenth of a round to consume it.
•	10 feet per round in an air-solid mix (cliff face, floor, person).
•	5 feet per round in just rock (ordinary rock gets no saving throw).
•	1 foot per round in water (but it draws everything to it like a sphere of annihilation).
Notes: the sphere begins at a 1-foot radius, and does not appear until the bolt either strikes something solid or reaches maximum range. The point of origin of the sphere remains constant, even if in midair.
The material component for this spell is an emerald worth at least 50 gp.
