Immediately on hearing that the Ants might offer some threat, Ironwolf quietly draws forth his Falchion. However, when Hulgyr takes off toward the ants, he calls for caution:
"Hulgyr! Wait! We should stick together, and I'm not much for fighting from Horseback."
He slips off his horse, and starts lumbering after Hulgyr, hoping his companion will slow, fearing he won't. As he walks, he swells to a height of 10' tall (Expansion, duration increased to 30 minutes, 3 pp) and in quick succession raises a force shield (+4 AC, 3 minutes) to ward off any attacks the ants may make.
Once this is accomplished, if Hugyr hasn't waited for him, Ironwolf will break into a run in an effort to catch up.
