Daemonic Speed

Daemonic Speed is a spell that has a casting value
of 7 and a range of 12". If successfully cast, pick 1
friendly Slaves to Darkness unit that has a Mount
and is wholly within range and visible to the caster.
Until the start of your next hero phase, you can
attempt a charge with that unit if it is within 18"
of the enemy instead of 12". In addition, roll 3D6
instead of 2D6 for charge rolls made for that unit
until the start of your next hero phase.
