Jolly Rager is a recurring skill in the Dragon Quest series.
Making its debut, it is learned by advancing to Rank 3 of the Pirate vocation in both versions of the game, and deals 50~70 damage to an enemy group for 0 MP. Despite being superior to Tidal Wave in terms of damage and use, it is inferior to Thin Air. In both versions, it is used by Rashers in the first fight alongside him and Stripes. It is also used by Shelligators, Gracos, the Water Spirit, and the Dread herring in the Temple Palace basement in the 3DS remake, due to Tidal Wave not being in said remake out of respect to the victims of the 2011 Great Eastern Japan Earthquake.
Learned by Desdemona, it whips up a storm with axe swings for 10 MP, making it useful for clearing mobs of monsters.
