Hailstone

When a druid casts this spell, one large hailstone or a swarm of smaller stones burst from his or her finger, traveling in a straight line to the target creatures. The

caster chooses which form the spell takes at the time of casting.

Large Hailstone. The caster creates one hailstone. This automatically hits one creature in a straight line from the caster for 1d4+1 points of damage. The large hailstone fractures on impact with a hard object (shield, helmet, metallic armor, a wall), inflicting 1 point of damage on any creature within 3 feet of the point of impact. The hailstone does not fracture on impact with soft surfaces. For every two experience levels the caster achieves above 2nd, one additional hailstone can be created (two at 4th, three at 6th, to a maximum of five at 10th level). These can be directed against different foes, provided all are at least partially within a 10-foot cube.

Hailstorm. The caster creates a swarm of smaller hail stones. These strike all creatures in a 10-foot cube for 1 point of damage. Each affected creature must also make a successful saving throw vs. spell or be temporarily stunned, losing its next action. At 6th level, the caster can affect a 20-foot cube, and at 10th level the area increases to a 30-foot cube.

This spell is ineffective underwater and when exposed to high heat (for example, a wall of fire provides complete protection). Since most of the hailstone effect is impact, it affects creatures immune to cold. Fire-based creatures with special vulnerability to cold-based attacks suffer from their normal penalty.
