Doom Reverb is an magic attack that is found in Super Mario RPG: Legend of the Seven Stars. When an enemy attempts to cast this special move, a hollow bell appears in the sky on top of the party member. Then the bell rings, dropping out hollow notes onto one party member while it rings. When it is done ringing, the bell disappears. This special attack causes one party member to have the Silence status effect. This special attack can be blocked by wearing a Wake Up Pin, Safety Badge, Safety Ring, Lazy Shell or a Super Suit. This special attack is normally used by Shy Guys, Sling Shys, Ding-A-Lings and Carriboscis, and it seems that the unused subspecies of Hippopo, Crippo, would use this attack too.
