A creature that starts its turn in the ooze\xe2\x80\x99s space is subject to its secretion.. The ooze\xe2\x80\x99s space is  difficult terrain . \n'b'  Secretion . A creature engulfed by the stonebuilder ooze, or hit by its slam  attack , must succeed at a DC 16  Dexterity  saving throw or become  restrained  for one minute. A creature that spends an action trying to remove the resin is entitled to another saving throw at the end of its turn. After 1 minute the resin hardens into stone, and requires either magic or an hour\xe2\x80\x99s labor with appropriate tools to remove. \n'b'  Actions \n'b'   Multiattack .

The ooze raises itself up into a wave taller than a man and surges forward 20 feet. \n'b'  Tactics \n'b' Only found outside its lair at night, the stonebuilder ooze invariably tries to Engulf and Slam opponents, and will fight to the death, not recognizing when it is outmatched. \n'b' Description \n'b' This enormous ooze, twenty feet or more in diameter, has a dull, pebbled surface, strongly resembling local rock and sand. It flows with a curious rippling motion, occasionally rising into great waves. \n'b' Stone builders secrete an acidic resin that they combine with dust and sand to create a sturdy stone-like material, which the ooze builds up into a rough cone, pocked with entrance tunnels. In the heat of the day, the ooze takes shelter from the sun inside its stoney home, and at night it emerges to hunt. \n'b'  This One is Just Right . The stonebuilder\xe2\x80\x99s conical homes are as strong as solid stone, 20 or more feet wide and high, and have walls 2 to 3 feet thick. The cones are a marvel of engineering, for they remain cool even under the hot desert sun. They are consequently prized as housing by creatures that are able to seize them from their oozy creators. But woe to the intruder still inside when its owner returns!'
