From LSWiki

The ability to enchant an ordinary wooden shield with extraordinary protective capabilities. After some time, this enchantment will consume the object. - While wielding the shield, it will absorb some of the attack from whatever is fighting you. It will be most effective against ordinary attacks, least effective against attacks that indirectly target one's biological integrity (such as disease and poison), and moderately effective against other sorts of magickal and elemental attacks.

• Example:

"Your square light-lined oaken shield pulses with blinding brilliance as it asborbs some of a bright-green-winged blue-skinned hermaphroditic sprite's attack."

Usage

concentrate on being enveloped by the <shield>
