Each aspect of Eurmal gets two Divine Spells. I'm not sure what the other spell should be for the Liar aspect, but here is my take on the Lie spell:
Lie
Duration Instant, Rank Initiate, Ranged
This spell is cast immediately after the trickster has told a lie, with the words "And you believe me". All those hearing the lie are forced to believe it, while they are in the company of the caster. Once they leave the caster's presence, and any time subsequently that they think about what they have been told, they make a Persistence test and on a success, the compulsion ends and they may re-assess the truth of what they have been told. When this spell is cast, the caster must also roll Persistence, and if the result is a fumble, they believe the lie themselves. The only ways that they can snap out of this belief are Heal Mind, or if their mind is dissassociated from itself through Befuddle, Madness, or similar discombobulation effect, or a further use of the Lie spell by another trickster that directly contradicts the first lie.
