Special Traits

  • Fire Friend. A brown mold does not take damage from fire. Instead, it heals that amount. If the available healing is greater than the brown mold’s maximum number of hit points, its maximum hit points increases by that amount.
  • Cold Sensitive. Magical cold damage instantly and automatically kills a brown mold.

Actions

  • Spore Burst. The brown mold releases spores that burst out in a cloud that fills a 15-foot cube centered on it, and the cloud lingers for 1 minute. Any creature that ends its turn in the cloud must make a DC 13 Constitution saving throw, taking 36 (8d8) necrotic damage on a failed save, or half as much damage on a successful one. Additionally, the target’s hit point maximum is reduced by an amount equal to the damage taken. This reduction lasts until the target finishes a long rest. The target dies if this effect reduces its hit point maximum to 0.

About

Found in dark caverns and remote subterranean passages, the brown mold waits patiently for victims to pass by. Less than an inch thick but spreading over a five foot patch of stone or wood, the tan to dark-brown mold seeks warmth to help it grow. Small bumps along its surface store thousands of spores waiting to be released into the air.

Any living creature that passes within 5 feet of the mold will be attacked by a burst cloud of millions of spores. Any caught within the 15-foot cloud may be overcome by the spores, dying within moments. The spores grow within their new host and crawl back to the main body of the mold, reattaching and adding needed nutrients. Each new victim adds another five feet to the mold’s size.

The brown mold craves warmth and heat; attacking it with fire heals damage and doubles its size. Cold spells will kill the brown mold for good.
