Chromatic counter

You manipulate the elements to negate and counter spells or hazards. When the damage type acid, fire, cold, poisen, thunder, or lightning is dealt within range the caster must discribe in detail how he negates that damage, for example: i create a wave to drown out that fireball, or i create a small tornado to redirect the green dragons poison breath. When you do this you can choose any creatures within range, those creatures then get immunity to that damage for the spells duration.
