One of the most useful spells that druids have at their disposal, is
the art of taking the immediate surrounding elements of a target, and
tuning them so they protect the target. Using the air, water, light, or
whatever else happens to be available, they are able to create a barrier
that is capable of absorbing and deflecting damage of any kind away from
the target. This spell's good is evident as the air around the target 
'wobbles' whenever the flexible, or flex for short, shield deflects
damage away.
