Now that there was only one creature left, Tatsuo switched tactics slightly. Since he still couldn't get close to check on the fallen travel companion, a different spell was in order. He rubbed his hands together, building up static electricity before clapping his hands towards the creature, sending a bolt of electricity its way.
Ear piercing scream -> electricity. DC 20 Fort save for half damage. If it fails its save, it's dazed for 1 round.
SR: 1d20 + 6 ⇒ (11) + 6 = 17
Electricity damage: 3d6 + 4 ⇒ (4, 5, 6) + 4 = 19
