Defenenus

This spell summons a translucent shield around the caster. Outsiders may see though the shield but can't get into the area of the shield unless allowed by the caster. The shield takes the form of a bubble around the caster. Any attacks or spells used towards the shield are invalid unless it is a spell to make the shield disappear. The shield however, only lasts for a maximum of 1 minute and should be used sparingly. This spell cannot be spammed and has a cool down of 5 minutes. A dice is not required to use this spell.
