Toughening Transmutation
( Complete Mage, p. 48)[General]
Casting a transmutation spell briefly transforms your skin or that of an ally into sterner stuff.
Prerequisite
Spell Focus (transmutation) or transmuter level 1st,
Benefit
Whenever you cast a transmutation spell, you can choose to grant yourself or any one creature targeted by the spell damage reduction 5/magic. If the creature already has damage reduction (of any type) from another source, you increase that damage reduction by 5 instead. This effect lasts for 1 round.
Special
A transmuter can select this feat as a wizard bonus feat.
