Synopsis
cast 'spell shield'
Description
This spell conjures forth a field of negative magic, which surrounds the caster and will absorb one offensive spell of 50% complexity or less. Spells from 51-75% complexity may be reduced in power by half.
Spell shields cannot absorb magic spells greater than 75% complexity - if the shield is struck with a spell of that magnitude, it will vanish immediately.
The spell shield will last until it is struck by an offensive spell, or its duration expires. While the shield is in place, the caster's magic will be drained due to the effort required to keep the shield active.
