Bubble Shield

A bubble shield is a round shield with defensive enchantments. When activated, it forms a protective bubble around its user, protecting them from harm. Unfortunately, the barrier goes both ways and it is just as difficult for the user to strike those outside of the bubble as it is for them to strike him. The Bubble blocks physical attacks and most spells as well. 
== Variants ==
The Bubble Shield can also come in the form of a necklace. This is a favorite of mages as they can feed it their own mana to recharge it, giving them a powerful defensive option.
=== Skin Tight ===
The Skin Tight variant of the Bubble Shield does not form a bubble so much as a protive layer around its users body. It enables them to continue to use weapons to strike their foe, however, it still prevents the user from casting spells on others. 
=== Reflective ===
The Reflective variant of the Bubble Shield can turn the force of those who strike it against them, repelling and returning physical and magic attacks alike.
=== Big ===
The Big variant forms a bubble in a six foot radius around its user. It is intended to be used to trap a foe in close combat and prevent their allies from aiding them.
