Ebony mail with selective shield charge knock back effect instead of the poison cloak.  When you're attacked... BOING!  The attacker is repelled and their stamina is drained.  If they persist it will eventually kill them.

You'll find the shields up armor in the player's home chest.  A house warming gift, enjoy!  Should not harm anyone who isn't attacking you (like your follower.)  Will harm brawlers, take it off if you're challenged to a fight.  

Revision 3  Added shield, boots and gauntlets.  Shield has spell breaker and fortify block enchantments.  It also deflects arrows.  Boots have muffled enchantment.  Gauntlets have fortify unarmed damage enchantment.  All armor weighs nothing to improve sneaking.  Removes ebony mail sneak effect so your vision isn't obscured while sneaking, better for archery.

Revision 1 uses the voice push effect from shield charge.  Revision 2 uses the same script as Jeek Half-Dragon's unarmed weapons which renders opponents immediately vulnerable to damage after being knocked back.  My thanks to Ominousvoice for the weapon push effect script.
