The boulders you hurl explode upon impact, laying waste to nearby creatures.

Prerequisites: Smoking Boulder, base attack bonus +13, heat rock special attack.

Benefit: You can infuse rocks thrown as part of an attack action with volatile fire energies, adding one of the following effects to a thrown rock affected by your Smoking Boulder feat.

• Choking Smoke: All creatures in the affected 10-foot-radius spread are nauseated for 1 round.
• Concussive Blast: Creatures in a 10-foot-radius burst are deafened and staggered for 1d4 rounds (Fort negates).
• Incendiary Explosion: The creature struck by this rock takes 4d6 points of fire damage, other creatures within a 10-foot-radius burst take 2d6 points of damage, and all affected creatures catch on fire. A successful Reflex save halves the fire damage taken and negates catching on fire.
