Ring of Fury

Bound spell (Power level 3)
The Elves are justly famed for their magical rings, and the black iron Ring of Fury is one of the most feared.
This ring may cast its Bound Spell once per Magic phase like an ordinary spell. The spell requires no Power dice to cast, all the power required is provided by the ring itself.
The Ring of Fury contains the Fury of Khaine spell described in the High Magic spells on page 29.
After each use, even if it was dispelled, roll a D6. On a roll of a 1 the power of the Ring has been exhausted and it may not be used for the rest of the battle.
