SQL counting all rows instead of counting individual rows

You're missing GROUP BY, so it's counting everything instead of grouping by some columns.

LEFT JOIN
(
    select `ID` as `AuraID`, `Status` as `AuraStatus`, count(*) as `Aura`
    from messages_aura
    GROUP BY AuraID, AuraStatus
) aura ON (var.Poster = aura.AuraID AND var.ID = aura.AuraStatus)
