Evince Lineage (3.5e Spell)

You bring out the hidden heritage in a creature, granting them a racial template with the word “half-” in the name (some examples include half-fiend, half-celestial, and half-dragon) for the duration of the spell. Which templates are allowed to be added by this spell may be left to the discretion of the DM, but the Challenge Rating adjustment for the affected creature (as a result of gaining the template) may not exceed an amount equal to CR +4.
