About this delicate and unadorned silver amulet the Winds of Magic boil with a storm's fury, confounding the wits of enemy Wizards. 
The Amulet of the Tempest may only be taken by a model in a Sea Guard Garrison Army of Infamy.  Whilst within 9" of the bearer of the Amulet of the Tempest, enemy Wizards cannot add their Level of Wizardry to their Casting rolls.
