Lust

Lust is a psychic energy created by humans experiencing extreme sexual desire or gratification. It is a primary food source for demons, and is most commonly extracted from humans.

As a Mechanic
The Lust system is a game mechanic in Rise of Velshara. Because monsters in the Grand Cauldron are able to transform humans simply by bringing them to climax, the heroine Layla must resist reaching climax while she battles her opponents. If Layla's lust reaches 100%, she climaxes and immediately experiences a game over. Lust can be reduced by using the Focus special ability or by drinking Anaphrodesiac.

Because Land of Velshara takes place outside the Cauldron, the lust mechanic is not used, as monsters cannot transform the heroine Pella Primrose by making her climax.
