Miasmic Mirage

Until your next Start of Turn sub-phase, the
target enemy unit suffers a -2 modifier to its
Movement characteristic (to a minimum of 1)
and cannot march or charge. If this spell is cast,
the effects of any other Hex previously cast on
the target unit immediately expire.
Around the feet of the enemy, the earth itself shifts
and blurs, causing warriors to trip and stumble upon
half-imagined obstacles.
