Revamped JoF

JoFs now add up to 3 damage to the base damage of a touch spell, basically taking it from spirit hammer damage levels to scimitar damage levels. This scales with HPs, granting 1 bonus damage at 60, 2 at 80 and 3 at 100 HPs.

However, just as with a real scimitar, you will take a -20 penalty to SP for each jewel used. Faren spells do not take a penalty, however.

JoFs now also have a lot higher durability and no longer consume mana. They basically allow a mage to fight on par with a warrior, at the cost of severly gimping their non damage spell casting.
Updated flavor text to reflect new properties.
