Hailstorm

Evocation [cold]
Tier: 3
Components: Verbal, Somatic
Casting Time: 1 major action
Range: 60 ft
Effect: Cone of ice
Duration: Instantaneous
Saving Throw: Reflex half
The fearsome blast of ice and snow drops most of the goblins, and the last few collapse after a few shivering steps.

This spell launches a blast of ice shards and freezing cold from your hand. The blast deals 4d6 damage to creatures caught within it. Creatures who fail their reflex save take an additional 2d6 on their next turn.

Augmentation:
For each extra spell point you invest, you can increase the secondary damage by 1d6. You can increase the secondary damage of the spell until the total damage of the spell equals [caster level + 1] d6.

If you cast this as a tier 4 spell, creatures who fail an additional fortitude save are fatigued.
