Beasley's Brittle Sticks

Causes a stick to become brittle, making a more than normal amount of noise if broken. The sticks can be placed on a path as an alarm. If a Brittle Stick is thrown into a fire, within 1d4 rounds it will explode. The explosion of a single stick itself is not dangerous, but can cause sparks and embers to fly out of the fire. If more than 5 sticks are bundled together, they have a 25% cumulative chance per round of spontaneously exploding.

The change is permanent, unless dispelled or soaked in water, which eliminates the enchantment.
