1st-level Spell: Foolish Fire

Whispering (Evocation)

Harmless, ghostly-blue flames suddenly appear around each object in a 20-foot cube within range as flowing wisps of light flicker in and out of the area. Those who speak Whisperic see the wisps of light as lanterns carried by vague humanoids.
Any creature in the area when the spell is cast must make a Dexterity saving throw. On a failure, they are also outlined in ghostly-blue flames. For the duration, affected creatures and objects shed dim light in a 10-foot radius.
Any attack roll against an affected creature or object has advantage if the attacker can see it, and the affected creature or object can’t benefit from being invisible. Additionally, if an affected creature is good or neutral, they also hear faint giggling or laughter emit from the wisps, whereas an evil-aligned creature hears only faint screams.
