Sangius curses as Eris speeds over the top, "Fool, I have some spells to cast, stay in the shell hole ((Hole J))" he then turns to the rest of the officers, "Ma'am, I have some spells I wish to cast on us, if we could rendezvous in that shell hole ((hole J)) I can catch all of us in the range."

He then takes a ladder and scurries up it with surprising agility, followed closely by Lavitus.

Is it possible to assume that I had cast mage armour before the whistle went? If so I Double move to hole J.
If not I cast mage armour and single move to ridge G.
