Elemental bane

Elemental bane was a transmutation spell that temporarily suppressed a creature's resistance to a chosen element and amplified its effect of the target.

Effects
The caster chose one element out of the possible options of acid, cold, fire, lightning, or thunder, then cast the spell on a creature within a range of 90 feet (27 meters). More creatures could be affected by more powerful casters. If unable to resist, the affected creature lost any natural or magical resistance to the chosen element, and took additional damage every time it was damaged by it. The effect lasted for 1 minute, as long as the caster kept concentrating.

Components
The spell required only verbal and somatic components.
