GREATER MEDUSA: 3/rest an only be activated while blocking -emits a frontal attack that casts greater fear...those who save must make a save vs petrification passive: immune to fear

Shroud of the Gargoyle:3/rest can turn yourself to stone with 500 dr Admantine for 60 secs or until next action ie attack or spell, healing is still permissible from ally passive: immune to petrification

Amber Eye of the Beholder: 3/per rest while blocking casts dispel magic without save in a radius of Great Cleave passive: you gain true seeing (60)

Just a few ideas but shields need something more...like paralyze effect, Knockdown winds, healing aura, globe of invulnerability etc whether its on the item itself or via augment
