Magic Items pricing

Finally, in order to allow Casting Items with a given number of uses per day and make them compatible with Gurps Magic (and thus creating a complete framework for HOW enchantment works in Dungeon Fantasy):

Add another option to the Powerstone spell, after "Exclusive" Powerstones (M70).

"Unstable Powerstones"

Alternatively, instead of being more energy efficient, exclusive (and only exclusive) powerstones can be made to recharge completely in a single day in Normal mana (1 point per day, in low mana; unaffected by high or very high mana). However such enchantment is inherently unstable: if anyone tries to enhance the capacity of an unstable powerstone beyond 10 energy points, or tries to remove it from its dedicated item, the powerstone instantly shatters.

An item being enchanted in this way must have a value equal to $20xP^2 + $80xP, where P is the target capacity of an Unstable Powerstone.
