A brown mold does not take damage from fire. Instead, it heals that amount. If the available  healing  is greater than the brown mold\xe2\x80\x99s maximum number of  hit points , its maximum  hit points  increases by that amount. \n'b'  Cold Sensitive . Magical cold damage instantly and automatically kills a brown mold. \n'b'\n'b' Actions \n'b'\n'b'  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\xe2\x80\x99s 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. \n'b'\n'b' About \n'b' 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. \n'b' 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\xe2\x80\x99s size. \n'b' 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.'
