Reverb (5e Spell)
From D&D Wiki
|Casting time:||1 action|
|Duration:||Concentration, up to 1 minute|
You touch a creature and words appear along the appendage you touched, causing the target to be bombarded with sound. As an action, you touch a creature and think of a word or sound. The creature must then make a Wisdom saving throw against your spell save DC. The creature must make this saving throw at the start of each of its turns until the spell ends. If the creature fails, it must suffer one of the the following effects:
-You think of a sound, such as thunk, whap, or bam. This sound then loudly bombards the creature's ears, causing them to be stunned and deals 1d6 + 2 psychic damage at the end of each of it's turns. The sound stops if the creature succeeds the saving throw.
-You think of a word or phrase, such as "Believe me!" or "I hate you!". This sound then plays in your voice, repeatedly playing in the creature's ears. If the creature fails the saving throw, it believes the words it hears and is convinced they are true. If the creature succeeds, the creature does not believe the words it hears, causing the spell to end and the creature to gain resistance to the spell for 1d4 hours.
