Fulgurate Mushrooms (CR 4)1
Ranging from pale sky blue to deep sapphire caps with cloudy white stems, fulgurate mushrooms are typically found underground or in areas where the ground is damp and soft (marshes or riverbanks, for example). A typical patch covers a 10-foot area. When touched, the mushrooms send out a burst of lightning that deals 3d6 points of electricity damage to any creature within 10 feet of the fulgurate mushroom patch. A successful DC 16 Reflex save halves the damage. Fulgurate mushrooms are instantly destroyed when they release their lightning blast.

If a patch of fulgurate mushrooms is hit with a cold-based effect or attack, it immediately releases its lightning burst at double the potency, increasing the range to 20 feet and damage to 6d6 damage. The Reflex save does not change.
