The boss of this large black shield resembles a deformed skull of tarnished silver. The shield bears many dents and scratches from past battles.
The Shield is a +5 heavy steel shield that makes its bearer unnaturally strong and resilient like a rune giant, granting a +6 enhancement bonus to Constitution and Strength as long as the shield is readied. As a standard action, the bearer can increase his size by up to two size categories, to a maximum of Gargantuan. For each size category increased, the bearer gains a +2 size bonus to Constitution and Strength and takes a –2 penalty to Dexterity. The bearer can shrink back to his normal size with another standard action; the effect also ends if he loses the shield.
When readied, the Shield also grants the bearer spell resistance 31. The bearer can ready an action to attempt to reflect a spell; if a spellcaster fails her caster level check to overcome the spell resistance granted by the shield, the shield’s bearer can reflect the spell back at its caster as per spell turning.
The shield explodes if an enemy successfully targets the bearer of the shield with a spell that overcomes the shield’s spell resistance and then, within 1 round, succeeds at a sunder combat maneuver check against the shield that deals enough damage to destroy it in a single blow. The explosion of the shield’s destruction deals 12d8 points of sonic damage to each creature and object within 30 feet (no save).
