Level: 2
Range: Touch
Duration: 1 turn/level
Components: V, S
Casting Time: 1 round
Saving Throw: Special
Area of Effect: Special

By using this spell, the mage
can temporarily acquire the ability to use a nonweapon
proficiency known to another creature. The caster must
touch the creature already possessing the desired skill. If
the creature is willing to transfer his knowledge of the proficiency,
the transfer takes place without difficulty. If the
creature is unwilling to transfer the proficiency, the creature
is entitled to a saving throw versus spells to prevent
the transfer from occurring. The creature touched does not
lose his knowledge of the proficiency, but merely allows the
caster to know the proficiency as well. Only nonweapon
proficiencies can be transferred by the spell. Other skills,
abilities, powers, or types of knowledge will not transfer.
The mage’s level of ability with the proficiency is exactly
that of the original owner, even if the appropriate ability
for the proficiency differs between the caster and creature.
