Give Them No Respite: The Akhelian King and his councillors understand the vital importance of the raid their army is carrying out, and will not allow the warriors under their command to tarry for even a moment.
You can use this command ability
in your hero phase
if the Akhelian King
from this battalion is your general, and the Isharann Tidecaster
and Isharann Soulscryer
from this battalion are within 3" of the general. If you do so, pick up to three friendly IDONETH DEEPKIN units that are wholly within 12" of your general. Add 3" to the Move characteristic of the units you pick until your next hero phase.
