Heroes 5 - Haven Creatures: Imperial Griffin - Imperial Griffins are the fastest troops of their Empire. They excel in skirmish attacks, flying into enemy ranks or diving from the sky above the battle. The Imperial Griffin's statistical upgrades are solid, but not spectacular, the biggest changes coming in the attack and defense values, a total increase of 38%, but it is also the Battle Dive ability that contributes to the increased cost (as well as the shiny armor). The Imperial Griffin is Haven's ultimate offensive weapon, and its fastest unit, too.
