True Gryphonheart Blade in Heroes 4

Increases the hero's Melee Attack and Melee Defense by 8. It also increases the Attack of all friendly creatures by 40%. Only a Gryphonheart can use it in battle.

This ancient sword has been passed down the Gryphonheart line of kings and queens for centuries, but it wasn't until recently that a wizard cast a spell on it assuring that only one of Gryphonheart blood could draw it from its sheath.
