A sense of security fills you as you complete the spell. As you touch the intended target of the spell, the feeling lingers for a moment before fading.
This abjuration grants a creature and its equipment complete immunity to damage from one of the five energy types—acid, cold, electricity, fire, or sonic. Energy immunity absorbs only hit point damage, so the recipient could still suffer side effects such as drowning in acid, being deafened by a sonic attack, or becoming immobilized in ice (and thus helpless).
