The gibbering arm consumes a willing or  unconscious  creature\xe2\x80\x99s arm. That creature becomes its host. The creature\xe2\x80\x99s arm is replaced by the gibbering arm and cannot wield shields or weapons, including two-handed weapons, but it can lift, drop, hold, push, and grasp things. The arm can perform the somatic spell components of spells. The arm acts as a  shield , granting its host a +2 bonus to AC. Additionally, the host\xe2\x80\x99s  Strength  score increases to 18 if it is less than 18. \n'b'\n'b' ACTIONS \n'b'\n'b'  Bite .  Melee Weapon Attack : +6 to hit, reach 5 ft., one creature.  Hit : 7 (1d6 + 4) piercing damage. A creature hit by this  attack  is  grappled  (escape DC 14). Until this grapple ends, the creature is  restrained , and the gibbering arm can\xe2\x80\x99t bite another target. If the creature remains  grappled  in this way for 1 minute, it becomes the gibbering arm\xe2\x80\x99s host. A lost limb can be restored by effects such as the  regenerate  spell. \n'b'\n'b' ABOUT \n'b' Gibbering arms have dense wormlike bodies of liquified flesh covered with sets of eyes and mouths from different creatures they have consumed, with each end of their tubular form leading to a toothed maw surrounded by splayed tentacles. They are terrifying to behold, and maddening to play host to. \n'b'  Mouths to Feed . Gibbering arms have only one goal: to feed. Though they prefer flesh found in the wild, these creatures readily devour organic and inorganic material alike, seeming sated only in fleeting moments while feeding. Gibbering arms can survive in the wild independently, hunting like great worms, but each seeks to bond with a host to fulfil their true potential for consumption. If a gibbering arm is found without a host, it is likely because something did not survive the attachment process, which involves the aberration consuming one of its prey\xe2\x80\x99s arms and latching itself to them at the shoulder. \n'b' Leeching off of their host\xe2\x80\x99s metabolism and driving them to unendingly seek sustenance for the both of them, gibbering arms usually drain and eventually devour weaker hosts, and only the strong can withstand them. \n'b'  Whispers of the Past . When a gibbering arm consumes a creature\xe2\x80\x99s body it is absorbed into its mass, the creature\xe2\x80\x99s mouth and eyes appearing on the arm within a few hours of consumption. Though their bodies are consumed, the psychic remnants of the mouther\xe2\x80\x99s victims remain; the eyes of these creatures often appear to be in a state of confusion, pain, anger, or terror, their mouths whispering incoherently. Gibbering arms without hosts will grow into gibbering mouthers after consuming enough food to undergo the metamorphosis. \n'b'  Alien Influence . The gibbering arm gives its host the following flaw: \xe2\x80\x9cMy hunger is insatiable, and the hungrier I get the louder my arm\xe2\x80\x99s whispers become.\xe2\x80\x9d'
