Käännös - Latina-Englanti - Fortuna exprimitur artibus falsis

The official translation, provided by the this bands homesite, is as follows:

Luck is formed by misleading means
And the liar has to be remembered.

CC: dramati

"mendax" is an adjective,not a noun and fortuna has a lot of meanings so there was many alternatives for my translation and i wasn t so sure of it , so thanks for the message.
