Winterhaven
Fang the Dire Wolf will hang back to stay near Urval the 'Giant,' but he will rush out to meet Tarrk two squares before Tarrk reaches the foes. The wolf's initiative is below.
So unless you can beat a 24, the wolf will attack Tarrk first to get this cotillion started: the wolf comes close to Tarrk and activates his prepared action and Tarrk skewers the wolf in the meat of his left hip, eliciting a howl (-22 hp, OUCH!). The wolf is definitely in pain, but keeps coming. It lunges at Tarrk's throat, teeth bared, but it misses.
