All in the Family (3.5e Spell)

''This spell is commonly used in inter-species wars to devastate the opponent’s side with a discriminatory plague or grant all members of a particular force the same benefits. It’s quite helpful for all of the non-humanoid enemies the average caster may encounter.''

You may use this spell to target any creature under the effect of a condition, disease, or any buffing or debuffing effect with a duration longer than “Instantaneous”. All creatures within 30 feet that possess the same creature type as the spell’s target must immediately make a saving throw of the same type and using the same DC (if necessary) or gain the effect possessed by the original target, whether positive or negative. Spell resistance and immunities apply normally, but only if those are offered by the copied effect. The transferred effect has the same duration that it did for the original target.
