You summon swarms of vermin to harass your enemies.

Insect Swarm

At-will, std, ranged, concentration, 1 energy; you summon a swarm of small insects (ants, beetles, flies, etc) which occupy 1 square within range. The swarm remains while you concentrate, and obeys your commands (swift action to give a command verbally).

• The swarm's Hit Points are equal to a medium damage roll.
• The swarm is immune to non-area damage, but any creature with feet can spend a standard action to stomp, causing their unarmed damage to the swarm.
• The swarm can move up to your speed on your turn as part of your movement.
• The swarm has one hostile ability: on your turn, it can occupy the same square as a creature. The creature suffers light piercing damage, and must pass a Con save or be nauseated (Con ends).

Rat Swarm (rank 2)

At-will, std, ranged, concentration, 2 energy; you summon a swarm of rats which occupy 1 square within range. The swarm remains while you concentrate, and obeys your commands (swift action to give a command verbally).

• The swarm is immune to non-area damage, but any creature with feet can spend a standard action to stomp, causing their unarmed damage to the swarm.
• The swarm can move up to your speed on your turn as part of your movement.
• The swarm has one hostile ability: on your turn, it can occupy the same square as a creature. The creature suffers medium piercing damage, and must pass a Con save or be nauseated (Con ends).
